RepWalker Mutant Ra04

The RepWalker is a Shellmo module. Shellmo is an open source robot project with it's homepage at shellmo.org and a forum at shellmo.net. A Shellmo should have legs, a heart and eyes - you can find the eyes for my Mutant RA04 here http://www.thingiverse.com/thing:328939
I have designed this RepWalker Mutant RA04 based on Sho's original RepWalker. While he wanted a light weight robot to print on Shapeways (each sq cm is money) I redesigned all parts for my RepRap printer. This means material doesn't matter, no fine details and the focus on "easy to print" and robust to play with.
I also looked for easy to source muscles and designed RepWalker Mutant RA04 to be powered by hacked standard servos with a 40 x 20 mm (about 5 US$ at HK - I used this one with two ball bearings plus one brass bushing in the gear train for added smoothness and precision http://hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=44049). You can find some info on how to hack such servos in the net or on my
