Revision 2 - 3D printed parts

A project log for Locomatrix - 3D POV - a different approach

Let's use some rotary to linear movements to display things in 3D. I have no idea if this will work, but hey, I'm gonna try it anyways...

I want to have some clean, new and updated prints - so I had to basically redesign everything, except the gear parts. The gear that is stuck on the motor is bought and still on there. The motor will be fixed with screws and the standard screw size is M3 now. It's currently printing in full with 140mil layer height of orange ABS. I will update this log, as soon as the prints are done.

Exciting! One question--have you considered sending some of the more stressed bits (or those more prone to breaking, at least) out for SLS, maybe in nylon? I've had good luck with this material--it seems to be way more isotropic and generally stronger than FDM stock. It's not cheap if you make big parts, but might be worth a shot?

First, thanks for the skull :) 

I was quite happy with the white ABS prints so far, since the quality of the zortrax 3D printer I'm using is pretty good and clean. With the gray, massively-warped PLA prints from my printrbot simple it all got bumpy and wobbly - especially with the glued in M4 screw. The plan is to test the redesign first, check for any abnormal behavior, and measure currents and stuff :) 

I've just dropped everything into shapeways, would cost 70-100 EUR for all of them together, printing only the geared stuff at shapeways would be about 22 EUR in elasto plastic or around 18 EUR for flexible polished stuff, so this may be an option - but I'm not sure if the elasto plastic would be to elastic.
