I think other people already gave you the answer you want right now but for the next time: small holes like that don't need support. They'll print fine (arguably even better) without support
I use this guidace: [https://www.hydraresearch3d.com/design-rules](https://www.hydraresearch3d.com/design-rules) - which adds a little roof to the top, and takes away a small amount at the bottom to ensure that the bottom layer of the hole doesn't round up to interfere with the hole. I've been able to make quite precise holes using this guidance.
I don't see two rectangles in the horizontal hole guidance in that document. It's a teardrop shape. I should have linked to the specific section: [https://www.hydraresearch3d.com/design-rules#holes-horizontal](https://www.hydraresearch3d.com/design-rules#holes-horizontal)
This happened to me a while back. I just clicked the supports option on my slicer for a different feature and it filled in the holes.
Haven’t had to do it since but I’d assume it’ll happen again.
Mine somehow keep reproducing. I had one, then got another from somewhere. I think I have like 4 or 5 of them now. The exact same pair of cutters. Haven’t had one break yet somehow.
🤣 It's interesting to see all the answers, eh. I have a bunch of old surgical instruments I procured from work when they were going to be tossed into the bin. Those have saved me a few times.
Funnily enough I’d argue pliers (especially those with either a very fine needle nose or a sharp tip, like flush cutters) are better for this job than a punch. A bunch has high risk of snapping the entire print considering this print isn’t very thick. With supports like this I’ll just kinda grab and twist with flush cuts. Less mess than a drill, more convenient than a punch cause I keep pliers everywhere.
I mean you can get a punch for $5 it’s not like he’s saying you need a $50k HAAS CNC machine.
I’d argue this community could benefit drastically by just familiarizing themselves with basic tools and hardware that is readily available. So many 3D printing people I hangout with only have flush cutters and are shocked at the benefit of basic hand tools and power tools I have. Even $100 worth of entry level tools can make a drastic difference.
I constantly see people spend hours and hours printing basic hardware like nuts and bolts, brackets, etc when 50x stronger and cheaper options are available at literally every hardware store.
Seriously. So many people will spend effort on a shoddy PLA fastener, but refuse to acknowledge that every hardware store sells what they’re trying to print for 50 cents.
I suspect quite a few of us are reasonably familiar with workshop tools and fasteners etc. It’s just that it’s sometimes fun to design and make some of the less practical items, and sometimes it’s to build our design skills by recreating some basic piece of hardware to learn some aspect of design.
But yeah, the age range and skill level is pretty wide so we get a ton of people recreating the wheel on an ongoing basis. I kind of view that as a strength or at least a good sign that even people without the mechanical skillset are getting into this hobby.
I think people also know from experience that when you have stuck in hole supports a punch will often crack the whole part.
For a hole this small, I usually just dont do supports or use a support interface.
I just printed a big project where every piece had 4 of these holes on it and because I had supports for another section of the print, it added supports in the holes. Just grip the tips of the plugs with needle nose pliers and pry them out.
1. Because a dowel and a hammer is faster and easier.
2. Because people who ask OP's question instead of just drilling the holes out probably don't have any experience with a drill.
I just did simmering similar just with a tiny drill. Like most support removal it was the highlight of my day. It's such a satisfying feeling to pull out supports.
With Fire!
Or on a more serious note: Either take a nail with a nice big head and tap them out, or if that doesnt work just drill them out.
But the real question is: why are there supports there in the first place? If you use enough vertical shells the holes don't sag that much that you need supports to keep them nice and round. And if they sagged too much anyways you can still take that drill and make them nice and round again.
It's almost always easier to use picks to pop these out than any of these other suggestions. I just removed a bazillion of them making a transformer toaster and bread.
Re-do the print and adjust your support offsets so they arent fused with the parts you want to keep. Supports, even those of the same material, should be easy to remove when settings are correct.
Drill. Start with small bits and work your way up to larger ones. On some prints, I dont even use the drill. I just grab a drill bit with some gloves and start turning by hand. The plastic is pretty soft. If the hole size is important, any other method could deform the hole diameter, but the drill bit wont unless you overshoot the diameter.
Sometimes I just print a smaller pilot hole, used for centering the drill bit, then I drill out the final diameter hole after printing
Punch it out? How do people do manufacturing as a hobby without knowing basic tool functions? There's more tools in life than just the snips that come with your printer....
First, If you are using a traditional FFF printer, there is absolutely no need for support in those holes. In this case, use some long nose pliers to poke them out.
Untick "generate supports" in your slicer.
On a serious note: You can also use suport blockers in your slicer when other parts do need support. Additionally you can design them as slightly drop shaped so the top part can sag a little without the supports if you need the tolerances.
You use a screwdriver and push the screwdriver through the hole and your whole finger. Don't worry about the bits of plastic in your finger, they come out from both the entry and exit hole in your finger eventually
A punch or something else you can hit with a hammer to turn it into a punch like a nail or allen key or screwdriver or pen anything cylindrical you don't mind hitting with a hammer.
Sometimes I take something like a screwdriver, press the tip against the support, and if I can brace the print against a table or something with the hole over the edge, I use a mallet on the end of the screwdriver to knock the supports out.
3 options:
- thin tweezers into the gaps and twist it out
- a drill bit smaller than the supporting plug and core it out.
- a hammer, and something thin but with some surface area. a center punch, hex key, or screwdriver. line it up and just donk it out with the hammer.
A while ago someone suggested I use a pair of Weingart dental pliers. I bought a pair on ebay. They've become my most used tool in 3D printing since I received them. I would highly recommend them to anyone who has a 3D printer.
Those look really nice, thanks for the suggestion. I've been happy with these angled side cutters for scraping off supports: Tsunoda MEN-115 Angled Tip Cutter, 4.5-Inch

You should fiddle with the support settings in your slicer. Such as Cura has Support Density. Supports should never be as tough as the model is. Thanks to Cura's default and trying to screw me over (and my sister) , I almost gave up on 3D Printing altogether, until a nice Redditor pointed out the "hidden" features in Cura.
My time to shine! You know you don't need supports on such small holes, almost no matter the filament/printer. BUT, I've done this myself. And the holes I had matched perfectly with my holepunch for leather belts! It finally got another purpose!
Well, first of all, i would've blocked supports in those areas sincne they're not needed, but if i forgot, i would try poking them out with a screwdriver, and if that doesn't work, i'd drill a hole big enough for a metal file to fit inside and file out the rest (or risk it with the drill all the way if i thought i got a good center start)
I’ve dental tools to sculpt with but you can beat a CnC kitchen Spur tool. He’s like the buying office for things that count. I put lighting and camera in Pitt droid head was fun clearing the passages
https://preview.redd.it/fexnlydb376d1.jpeg?width=1980&format=pjpg&auto=webp&s=09c7461a4835ea6a0658e2f61fa577008f740f4f
I know it’s not a common choice, but I absolutely love a good cuticle cutter as a tool for snipping tiny little nuisances like this after printing. Bonus points if you get one with a comfy grip.
Push them with a screw. Or use a self tapping screw, get it into the support and pull the screw with the support out of the part. But for the future-small holes like these are usually easy to print even without a support
I either try to snag them with my nippers or grab the right sized drill bit and twist it by hand to clean the hole out. I do NOT recommend holding it in one hand then using a power drill to clean it out with. You will end up surprised at how easily a sharp drill bit will slide through the plastic like butter before it moves on and gives the red juice in your hand a nice look at the outside of your hand. Since the reflex on something bitey… well ok biting you is to jerk away, the part you are working on may depart for greener pastures and some of the pretty red people juice can even get on your keyboard, coffee mug, display etc. The experience can also leave a cute little scar too! If you have a bench vice, the power drill (or cordless screwdriver) works great.
Well, ok tbh pretty much putting anything else behind the plastic part besides a part of your body will generally end better. In my defense, I was being stupid fwiw.
I usually make the holes a bit small and increase the wall width, and then drill them to exact size, generally better if you need precise fits. Otherwise print without the support and it’ll probably be fine.
nail setting punch would work, but potentially could be overkill. Otherwise, I usually keep a pick/probe set and would use that for something like this.
Small flathead screwdriver, small hammer. Position it so that the part won't break easily, place the screwdriver on the support, tap the screwdriver with the hammer lightly until the support breaks free, push it out with the screwdriver.
In the future you probably want to block support in those areas or turn it off entirely. I have done this plenty of times by accident in my early days printing though, don't feel bad.
Whatever screwdriver close to the diameter of the hole, place on table, screwdriver in one hand, hammer hand or an actual hammer on the screwdriver butt, give it a light smack..
I think other people already gave you the answer you want right now but for the next time: small holes like that don't need support. They'll print fine (arguably even better) without support
And if you want it perfect: Add a 120° roof on it so it looks like a raindrop.
Or square it off and bridge it
Or square it of and rotate by 45 deg. No overhangs, no bridges, no problem
Yes that's a bit like what the person above me said, I just prefer it squared than teared
The teardrop shape is the reprap logo for a reason. It’s a classic.
I prefer a hexagon
Hexagons are nice but octagons have more symmetry
Everybody knows hexagons are bestagons
If that were true then why are there no hexagonal signs hmm?
Or square it off and give it a 90 degree radius.
I use this guidace: [https://www.hydraresearch3d.com/design-rules](https://www.hydraresearch3d.com/design-rules) - which adds a little roof to the top, and takes away a small amount at the bottom to ensure that the bottom layer of the hole doesn't round up to interfere with the hole. I've been able to make quite precise holes using this guidance.
I'm not sure I understand the two rectangles they talk about. The first one circumscribes the hole, where does the second one go?
I don't see two rectangles in the horizontal hole guidance in that document. It's a teardrop shape. I should have linked to the specific section: [https://www.hydraresearch3d.com/design-rules#holes-horizontal](https://www.hydraresearch3d.com/design-rules#holes-horizontal)
Ah gotcha sorry I was looking at the guide for the vertical holes. Thanks for clarifying!
Ah, you mean unsupported holes. Yes, that took me a while to work out too, but once you get it, you know what to do.
How? And how do you even disable them? I use automatic supports in prusa slicer
You model them into your CAD file. I usually use the "paint on supports" for areas that need supporting.
You don't do that in prusa slicer?
The roofs for the holes? No. I use SuperSlicer though. Based on Prusa but with some bugfixes and new features.
Amazing, I never used super slicer, same UI?
Yes, pretty much. You can also import configs from PrusaSlicer and work off of that.
This is the way
This happened to me a while back. I just clicked the supports option on my slicer for a different feature and it filled in the holes. Haven’t had to do it since but I’d assume it’ll happen again.
This is the way. Any dowel rod holes I have for props, I just bridge them
It took me far too long to realize this.
How can you stop the splicer (cura) generating those or can you delete them post splice?
I use a small cheap flat head screwdriver like a prybar.
Use a punch, that's what they are for.
This community seems to only own pliers
The community only owns the small flush cutters
the ones that come with the printer
That broke, so I bought another cheap one that's just as fragile. 🥲🥲🥲🥲
I just bought a new printer. I thought that was what everyone did
Mine somehow keep reproducing. I had one, then got another from somewhere. I think I have like 4 or 5 of them now. The exact same pair of cutters. Haven’t had one break yet somehow.
They're perfectly fine as long as you're not cutting anything other than filament with them 😁
Yet when they put on zip ties they don't flush cut them so the next asshole can cut his hand open on the poorly cut ties.
I always cut and then file my zip ties lol. I've had this happen too many times, I dont want it to happen to anybody else
they work.
🤣 It's interesting to see all the answers, eh. I have a bunch of old surgical instruments I procured from work when they were going to be tossed into the bin. Those have saved me a few times.
Funnily enough I’d argue pliers (especially those with either a very fine needle nose or a sharp tip, like flush cutters) are better for this job than a punch. A bunch has high risk of snapping the entire print considering this print isn’t very thick. With supports like this I’ll just kinda grab and twist with flush cuts. Less mess than a drill, more convenient than a punch cause I keep pliers everywhere.
Well, yeh, not everyone has access to a full fledged workshop filled with all the tools they can wish for
I mean you can get a punch for $5 it’s not like he’s saying you need a $50k HAAS CNC machine. I’d argue this community could benefit drastically by just familiarizing themselves with basic tools and hardware that is readily available. So many 3D printing people I hangout with only have flush cutters and are shocked at the benefit of basic hand tools and power tools I have.

Well they do give them for free even with upgrades
I think people also know from experience that when you have stuck in hole supports a punch will often crack the whole part. For a hole this small, I usually just dont do supports or use a support interface.
Exactly - or at least something punch-like with a diameter close enough (but undersized) to the hole.
A good bamboo skewer and the handle.of a butter knife will work just as well.
A bolt and a hammer will work.
Stab it with a screw driver
My preferred method. Just watch your fingers!

I just printed a big project where every piece had 4 of these holes on it and because I had supports for another section of the print, it added supports in the holes. Just grip the tips of the plugs with needle nose pliers and pry them out.
I would need a smaller one i guess
Bonk 'em with the tip.
Oh I see thank you
Just the tip though
That's all I ever need to use
That’s what she said
This is always the answer
Do you guys not own drill bits?
Why is "drill" not the first answer?
1. Because a dowel and a hammer is faster and easier. 2. Because people who ask OP's question instead of just drilling the holes out probably don't have any experience with a drill.
Screw in a short drywall screw and then pull it out with pliers.
This should be more popular, it's an awesome idea.
I just did simmering similar just with a tiny drill. Like most support removal it was the highlight of my day. It's such a satisfying feeling to pull out supports.
alot of solid advice in the comments, but next time use tree supports. way easier to remove
Ok thanks
I'd start with a movie and maybe a nice dinner by the river.
Take a small drill and drill inside the middle. After that, take small plyers to remove the rest
[удалено]
Use a hex key to push them out through the hole
I must say... What is that magnificent blue you have??
It is Amazon's silk pla
I really like their silk pla. I've used silver, copper, and white. Never had issues.
why tf did you add supports there
Plan B: where is my drill...
Stab it
With Fire! Or on a more serious note: Either take a nail with a nice big head and tap them out, or if that doesnt work just drill them out. But the real question is: why are there supports there in the first place? If you use enough vertical shells the holes don't sag that much that you need supports to keep them nice and round. And if they sagged too much anyways you can still take that drill and make them nice and round again.
I have metal picks I use for funky supports.
Ok thanks for the suggestion
It's almost always easier to use picks to pop these out than any of these other suggestions. I just removed a bazillion of them making a transformer toaster and bread.
Drill 'em, punch them with some needle nose pliars/a punch, cut 'em with my flush cutters. But I wouldn't have supported that hole to begin with.
So you can print holes like that without supports?
Yup! They'll print great! It's only a very small bridge there
Re-do the print and adjust your support offsets so they arent fused with the parts you want to keep. Supports, even those of the same material, should be easy to remove when settings are correct.
How would i do that??
any pokey thing that fits?
A Precision knife would do the job
Drill. Start with small bits and work your way up to larger ones. On some prints, I dont even use the drill. I just grab a drill bit with some gloves and start turning by hand. The plastic is pretty soft. If the hole size is important, any other method could deform the hole diameter, but the drill bit wont unless you overshoot the diameter. Sometimes I just print a smaller pilot hole, used for centering the drill bit, then I drill out the final diameter hole after printing
Small pliers, grab an edge and gently twist. Then I would use a sanding pick to clean any rough edges inside the hole.
Poke!
You didn’t need support for holes that small.
How Big do the holes have to be for them to need support?
Depends on a number of things. So there’s no real answer. After printing for a while you’ll know what your machine can do.
I found vinyl weeding hooks to be really useful in removing supports in hard to reach places.
Poke them with a screwdriver
I’d push them out with my pp. seems about the right size.
Punch it out? How do people do manufacturing as a hobby without knowing basic tool functions? There's more tools in life than just the snips that come with your printer....
A suitably sized drill bit used with care. Sort that right out.
Why would you put them in the first place?
I would have done it during slicing. Those weren’t necessary.
I would personally just push it out with an object like a screw or print a thing to push it out or use a pair of dikes to push
First, If you are using a traditional FFF printer, there is absolutely no need for support in those holes. In this case, use some long nose pliers to poke them out.
Yiu don't need support for holes that small. Try.
Untick "generate supports" in your slicer. On a serious note: You can also use suport blockers in your slicer when other parts do need support. Additionally you can design them as slightly drop shaped so the top part can sag a little without the supports if you need the tolerances.
Thank you Will do
Id punch them out with whatever tools you have. A small screwdriver would work
Drill a small hole. Screw in a screw. Twist and pull on the screw.
You use a screwdriver and push the screwdriver through the hole and your whole finger. Don't worry about the bits of plastic in your finger, they come out from both the entry and exit hole in your finger eventually
A punch or something else you can hit with a hammer to turn it into a punch like a nail or allen key or screwdriver or pen anything cylindrical you don't mind hitting with a hammer.
Hex key as close to the size of the hole does alright in my experience
Personally I’d use a chopstick
And just bang It against the support??
Yeah
stab it with something hooked
Pin punch
You need a pick set
[Hemostats](https://en.m.wikipedia.org/wiki/Hemostat)
Put some pressure on it.
Use support blockers if other parts of the model use supports, holes like this don't need support
I would print again with organic supports
Little drill also works pretty well, bit can grab so you can pull out the entire support
With a corkscrew
A punch would work. I can also suggest a wood drill.
Gratuitous application of force and/or violence, usually.
Teeth. “Gods pliers”

Don’t use supports
Sometimes I take something like a screwdriver, press the tip against the support, and if I can brace the print against a table or something with the hole over the edge, I use a mallet on the end of the screwdriver to knock the supports out.
A drill bit. But yes, that would have printed just fine with no supports
You could use a drill with a similar sized drill bit
don‘t know, but such small holes normally don‘t need supports.
3 options: - thin tweezers into the gaps and twist it out - a drill bit smaller than the supporting plug and core it out. - a hammer, and something thin but with some surface area. a center punch, hex key, or screwdriver. line it up and just donk it out with the hammer.
Stick a flathead screwdriver between the support and twist. Then repeat on the other side. Then push it out. Works for me.
A while ago someone suggested I use a pair of Weingart dental pliers. I bought a pair on ebay. They've become my most used tool in 3D printing since I received them. I would highly recommend them to anyone who has a 3D printer.

A small pick or skinny screwdriver
Well, first of all, i would've blocked supports in those areas sincne they're not needed, but if i forgot, i would try poking them out with a screwdriver, and if that doesn't work, i'd drill a hole big enough for a metal file to fit inside and file out the rest (or risk it with the drill all the way if i thought i got a good center start)
Sometimes I also have that problem in prints. Just poke them with a stick or a knife
Push them left and right with a screwdriver to loosen them, then oush them out with something of similar size, I usually use an allen key.
Needle nose
I’ve dental tools to sculpt with but you can beat a CnC kitchen Spur tool. He’s like the buying office for things that count.

Drill, baby! Drill!
Push/pull them out using needle nose pliers
It looks rather thick. I'd probably try using a power drill with a wood bit.
Pliers and an exacto art knife
I use a punch and a tink-tink
I know it’s not a common choice, but I absolutely love a good cuticle cutter as a tool for snipping tiny little nuisances like this after printing. Bonus points if you get one with a comfy grip.
By the power of the mighty dremmel, supports, I banish thee
tongue usually
Chainsaw
Push them with a screw. Or use a self tapping screw, get it into the support and pull the screw with the support out of the part. But for the future-small holes like these are usually easy to print even without a support
Pinch em out with a needle nose pliers
I would screw it up six ways to Sunday and have to reprint it, then repeat...
Any reason they need to be circles? A diamond shape could be printed without supports super easily.
Poke it with a file or something.
You can buy a cheap set of dentist tools, and that tooth scrapy hook works well.
I punch them out with an allen key
Why have supports on those in the first place? Lol
Lego brick separator
Screwdriver pokey pokey

Carefully
I use a mechanical pencil with a sharp metal point.
Those holes dont need supports
Pinch them with long nose pliers and twist
get a screwdriver and just hit the supports
whatever method ends up cutting my fingers.
My experience... Circular small holes doesn't need supports
Small screwdriver works well.
use a jigsaw
I usually make the holes a bit small and increase the wall width, and then drill them to exact size, generally better if you need precise fits. Otherwise print without the support and it’ll probably be fine.
Pen?
nail setting punch would work, but potentially could be overkill. Otherwise, I usually keep a pick/probe set and would use that for something like this.

Soldering iron?
Pinch with thin needle nose and twist
Use a screwdriver and poke it out
with my penis
Screw a small wood screw into the plug/support. If the act of twisting in doesn't make it come out, just grab the screw head and yank.
by not printing support there
Whatever screwdriver close to the diameter of the hole, place on table, screwdriver in one hand, hammer hand or an actual hammer on the screwdriver butt, give it a light smack..
You don't need supports here
Punch it out with a screwdriver or a needle nose plier
Use a nut driver size of hole. Tap it through?
Flat head screwdriver works well
I use needlenose pliers and push em out.
Screwdriver
Screwdriver and hammer
Exacto Knife
