Jointy Bot Mk-2 Robot

Jointy Bot Mk-2 is an upgrade to my first jointy bot project. https://www.thingiverse.com/thing:3602449 I have incorporated M3 bolts with a 12mm shaft into the design in order to keep the joints tight. I have redesigned the head to fit together without the need for screws. All the parts are backwards compatible with the Mk-1.

I have Updated the stl files for the feet. The correct stl files for the feet are as follows:

right foot_round side.stl
right foot_hex side.stl

left foot_round side.stl
left foot_hex side.stl
