Well in seeing how tough the previous 3D printed gears were, I broke them :) so they were not that tough! LOL

So here's version 2.5 of the gears - I made everything beefier and also put two stages of planetary gears in there for more torque, less backlash, and just all around coolness :)

Here's a video of them working

and here's a few pictures for ya!

Had a request for the files - So Here they are! -Click Here to Get Zip File...- Solidworks, STL, and GCode so hopefully you can use something from this :)
