I had a little problem getting the little end piece to plug in. Any suggestions?

I gave it a super light sanding with 600 or 1000 grit (I forget) and I had to press it in REALLY HARD.
Like full body weight, upsidedown on the counter. Works surprisingly well!

thanks for uploading your remix version.
It's exactly what I was looking for as a quick and simple hand drill.

Printed this with not much hope. But it works so well!!!! Managed to drill through a piece of mdf and into the table in no time. printed with petg with 5 shells and 45 infill just in case.

Printed in ABS with my A8. Everything fits and works perfectly. Thanks!

In PLA the chuck doesn't hold the bit very well. So even drilling PLA it spins.

these things are seriously nice. durable, and they can drill pretty fast. i was putting some hardware up and didn't have a power drill on me and this chewed a hole pretty fast. it can be a bit hard on the fingers if you drill a lot, but that's unavoidable. you can wear gloves if that is the case.

Is there a piece missing from this?

I was wondering if you could upload the 123d source file. This would enable the community to adapt/improve the design without entirely redesigning the drill, like you had to do yourself.

Would be cool to see a full on pump drill like the kinds we used to use growing up; I guess you would need a ratcheting shaft and a coil or a spring or something to store the rotational energy.

i want to make an attachment for it to make it into a drink mixer.. but i think do do that i will need more secure way to hold the top of the drill handle when pumping it up and down.. i have an idea for this.

Is there a trick to getting the end piece to pop into the main shaft?

i am wondering the same thing.. I have an idea for a different head attachment that would give this drill more flexibility when needing to suspend it while pumping up and down.. like when mixing power into liquid..

Can u make chuck for drill 5mm?

Could somebody verify that I'm reading the name right, does the 1-5mm chuck file indicate it can fit a drill bit between 1-5mm? I'm planning on using a 2mm drill bit, want to make sure I print the right one, thanks!

Would be nice to get a response from the designer on this...

do you know if the file has changed, or if there are co mpatibility issues with Slic3r?
it had worked before, but now the handdrill file gives all sort of errors when i try to slice it.
also it would be great if it was possible to have the 3 parts separate.

The process seems quite tiring...
Perhaps this dude will be successful at operating this drill:

Awesome! Works really good.

I printed all 3 shafts in PLA at 0.3 and then two of the handrill.stl files at 0.1 and other than a little cleanup with a needle file everything just worked

Nothing more satisfying than successfully printing out design on a lowly $280 TwoUp with a $60 MK V-BV hotend while seeing people with much more costlier machines fail .... and I've only had this for a couple of months (I am however an EE with CNC and microcontroller design experience)

An amateur grade tool in the hands of a professional will always beat out a professional grade tool in the hands of an amatuer.

Good job on designing this essentially from scratch just by looking at and measuring an existing design, that's a skill that can take you a long ways and makes you very employable

What program did you use to make this?

If possable, could you upload the parts sepretley, I made two drills, and the ball joint keeps brakeing, and I have 2 spare parts left over when I try to reprint. So the sepprete parts would be useful. That would really help.

What is the diffrence between the chuck peices?

The interior diameter

Just so you guys know, if you don't want to tamper with temp settings and such, but the slider piece wont go on all the way, X-ACTO knifes are really handy for quickly slicing excess plastic.


How do you type so big Jw

20 megs a pop for those STL's?

just throw it into meshlab and clean up the file.

but I think the 20mb file has finer details on the spiral part of the body, so you should just slice the original file if your slicer software is capable of load a 20mb file.

printed one on PLA , but the handrill pieces wont fit... am i doing something wrong?

i had same problem.. the shaft is too big for the other pieces.. Can some one clarify are the sizes of the shaft and the other pieces need to be resized before printing?

i got it to fit by shaving s slitght bit of plastic off the end of the shaft... and a bit of plastic off the bit end wedges..the end piece nib was not very strong and was a big to big to fing in the ind of the shaft.. but probably can resolve that by a bit of scraping shaving some of the plastic

I had the same issue with the end cap. Filing the ball and socket a tiny bit worked wonders. Hope this helps!

I tried to make with PLA. Bad idea. Structure was not very strong.

  1. print with lower layer height plus wider stroke
  2. print with 100% infill
  3. print with higher temperature (but you might have to set 5%~10% inset (of the extrusion width) this way, else you can't fit the slider into the spiral body)
  4. print with 5% ~ 10% extra extrusion or 20% ~ 25% overlay (same as above, add some inset)
  5. ...... print with carbon fiber filament?

So weak. all 3 broke right after being made.

I haven't had an issue putting it together with 20% infill. What is the shell thickness that you are using? I have mine set to 0.8 mm.


Mine are extremely strong, and I'm using PLA and 20% infill? Is are printer like super or something?

What infill were you printing at? Might be worth a try at 100%.

I used 20 percent but then it doesn't use much infill. just putting the nuts in made all the 3 types break, I didn't use much force but then maybe PLA wasn't a good idea for building this.

I have used PLA for pretty much


yet still, it's all strong at 20% infill. Check the outer shell thickness, that could be the problem.

What a nice idea, sure I'll try to print it

Nice! im looking for this one. Can u provide a skp o source file? i need a remix for use with electric motor, ill share


If you go into the extension warehouse in Sketchup, it should be the 1st most popluar extension, otherwise, search for stl. There should be an export stl option in the file tab once you install it. That means it's put in right. Then click on file, import. Select the stl file, and it should be able to import it. May take a moment to load. If you don't see the stl file in the import file, check the types of files shown.

Man, using this drill just comes naturally to me. I could put holes in things all day long.

That's pretty freaking cool!

Are you printing yours standing up, like in the rendered pics? I have one from Performance3d and use it around the house all the time.

funny, and whats cool about this is we are using a new technology to make a tool that was developed over a century ago. spiral drills and screwdrivers go way back to the 1890's. bowser being a large manufacturer of them. i can remember my dad having one of them back when i was a little kid. that thing was an antique back then lol. nice job!

Hi - Jay from Performance 3-d here. Just wanted to chime in and clear the air. Once Speedy bought our aluminum arm kit and saw the included drill, he modeled up his own version as a cool CAD exercise, which he then wanted to share with the community. 3dprint.com (and later, 3ders.org) wanted to run an article on his drill but he insisted that they contact us instead, as it wasn't his original design, just his rendition. At the time, we had not made the files public, but as others noted have now done so on our downloads page.

We received a lot of good publicity from the articles and Speedy deserves good will and commendation for directing 3dprint.com to us when he could've easily taken credit. That was never his intention, and the fact that he did not do so shows his moral character.

So please stop with the undeserving comments. He did a very nice job modeling up based on our drill - and really, I can't even say it's our design since similar hand drills have been around since antiquity.

I can't help but laugh at the irony of someone on a Makerbot website accusing someone else of stealing ideas ......

Pot ... Kettle ...Black

Some of you really need to 'get a life" ..... As soon as I saw the bold face type in the description I knew the "usual suspects' were at work here tearing down someone else like the cyber-bullies they are ....

Your approach to design and community is refreshing. Thank you for clarifying, thank you for sharing.

The original portable cordless drill.
In this case a Persian drill it seems. As opposed to a Yankee.

Hey Jay.. When are you guys going to design one with the ratcheting like the old ones had.. lol J/K.. Great design by both.

Haha, I'll have to put that on my (never ending) to-do list!

You could be right about the helix, now I'm going to have to print them and put them side by side to see. I do know that ours has a more typical "v" thread while Speedy's is rounded (probably a half round). Also I know the end piece is slightly different as well.

Either way, just glad so many people think this is cool and are finding it useful.

I don't understand, did you design this yourself or just copy the one that Performance3D makes and sends out with their kits?

Edit: I read Performance3D's post, seems clear enough. I still think it would have been better to maybe start with their design as a guide, and then add new features or customization to make it your own.

He said he made it himself by looking at the one on the website, as it wasn't available for download at the time.

Well, Performance 3D has their STLs on their site for download : http://www.p3-d.com/twist-drill.html

Not sure if it is a direct copy or not, but I for one would never have known about this being out there.

Definitely one of those things you say why didn't someone think of this sooner?

It goes back even further, for instance the Dakota (Sioux) used a similar method (bow drill) to drill out the long stems on the pipes going back at least 1000 years ... considering is was made entirely of wood with no metal bits makes drilling out a 2 foot pipe stem a major accomplishment

Nicely done. Very cool little hand tool.

Sheilawnne, what are you doing here?
