Thingiverse - geekdaddio's Favorite Things

Notice: This is a project in development, and I intend to improve it over time. This draft will work, but it's hardly ideal. Caveat Emptor!

Update Jan 31st: I've uploaded Version 2, which is pretty much the same as 1.5 (which I've removed as a result) but comes with the "Hex Key Holder", which can be fitted with a standard screwdriver bit from a powertool to act as a crude "center". My experiments with using two such centers to drive the lathe weren't great, as one invariably ends up spinning and the piece stops. So it looks like the required parts at present are: Two Bearing-End-Body Sections, two Bearing-And-Tool-Fittings, A Boltplate and a Hex tool holder. You'll also want a Dremel Rest and a length of MDF/wood to bolt it all down to. And you'll need googles, and perhaps gloves, and a lot of sense.
For now, it is left to the user to figure out spacing of the body sections and how to align them. I'm working on improving that. :)

More Update: Really bad video of me demoing Microlathe: youtube.com/watch?v=6XXN6UkrnIw and a shot of the finished piece of dowel on my Twitpic: twitpic.com/y8jnl
Also, Microlathe was featured on Makezine! blog.makezine.com/archive/2010/01/tiny_printable_dremel-powered_lathe.html

Microlathe is a little dremel-powered woodturning/watchmaker's lathe that can be printed and bolted together with all those leftover M3 nuts and bolts that came with your Makerbot. In addition to the M3 nuts/bolts, you only require a 608 bearing (I got an extra one with my Makerbot) and an 8mm diameter spring to fit the bearing-end. You probably don't even need that spring.

So, if you have a Dremel handy, you can consider this "The Lathe That Came Free With The Makerbot"!

Microlathe is Parametric, and makes use of a "Global Parameters" script from which the others derive shared traits such as the radius of the bolt plates, etc.. you could try printing a larger one, but bear in mind the limited space you have to print the body portions, which are already quite large for a Makerbot.

MicroLathe makes use of shapes.scad, which was kindly released to the community under the GNU General Public License by Catarina Mota. Permission was explicitly granted for shapes.scad to be considered released under an Attribution, Sharealike license additionally in this case, to facilitate licensing crossover. Thanks a million Catarina!
Microlathe also makes use of teardrop.scad, which was provided kindly by Erik De Bruijn. Teardrop.scad is released under the GPL2 license, with the inheritance clause generously waivered in this case to permit release under a non-GNU license. I'm very grateful Erik, thanks!

I'd appreciate a small donation via Paypal if you find yourself using this to generate a profit (selling turned items, etc.), or if you just love it and want to show your appreciation. Otherwise, it's all yours to print for yourself or others! Just don't charge for it without asking me and informing the buyer that it's available freely here.
