World’s Smallest Cordless Power Tools, 3D Printed Of Course

What is this?  A circular saw for ants?!

There isn’t much information we could find on this one (sorry, no source files that we know of), but this little hack is so playful and fun, we just had to share it with you. [Lance Abernethy] has built both a working cordless drill, and circular saw using nothing more than a 3D printer, what seems to be a pager-type vibration motor, a tactile switch and a coin cell battery – you can see them both working in the video after the break.


[Lance] used an Ultimaker 2, running a 0.25mm nozzle, and printing at a 0.04mm layer height in PLA. As you would expect, the 0.25mm nozzle is needed for such small parts – it’s also close to the limit of what extruder can still squeeze plastic through. it greatly increases the chance of blocked or clogged nozzles.

[Lance] admits that the saw can’t quite cut anything just yet, but he does say that he has plans to make more miniature cordless tools.  We can’t wait to see how he might manage the mechanism for a jig-saw.

  1. Reminds me of a very small platform consisting of a lathe, drill press, table saw, grinder, air compressor and possibly a band saw. IIRC the entire thing was operated via a common drive shaft attached to each tool via belts.

    If I recall, they’re intended to make custom inks pens. I considered acquiring such a setup during my scale modeling days to fabricate custom pieces out of styrene plastic. This all predates 3D printing which is probably a boon to the industry. I can just imagine how intricate those scale models are now compared to the ones 30 or more years ago.

  2. I’m actually more interested in the platform that these tools are placed on?
    It looks quite intricate.
    These tools have been floating around the web for at least a year I think.

    I was not aware that you can print that fine and small though :)

          1. Nope. I created that banner in photoshop myself. I know ’cause I did it – I combined two images, and if you look carefully one of the tools (of the saw) is flipped as to fit the frame and make it look better(it’s backwards left to right). The handle of the saw is backwards, and the area above the saw is filled in with a stretched few pixels of the that image, and quickly blended with the smudge tool. Sorry man. Nice troll though.

  3. That’s amazing, fully functional too, can’t argue with that! Being able to create this sort of thing is really going to open up the doors for model making hobbiests to take the level of detail they can produce to the next level I’d have thought.
