third mutant
Hello friends,
tonight I finished the chassis of the RepWalker RA03 mutant. With this everything fits together as it should. Next will be to design an Arduino mount, a support for pumper switches at the front and at least the connection beams to the Shellmo top modul.

This is the result of the last 10 days. At the top Sho's original RepWalker - still waiting for the gear motors. From left to right - my first design for hacked standard servos as gear motor including the h-bridge driver. In the middle some design changes - even left and right parts are different. At the right the last mutant RA03 with good fit of all parts.

Side view. Please notice: this is the left side (SF L = Side Fram Left) But I assembled the claws in wrong orientation ... its 1:00 at night already - will change this tomorrow

All parts are modified from Sho's original to make it an easy printable design. One big mod is to change the axis diameter from 4 to 5 mm. I also eliminated the spacer washers and used this space for extra reenforcement of the axis. In general I have made all parts a little thicker. This is no problem for home printing because material is not that expensive like with commercial printers. All parts are printed with a layer height of 0.5 mm and extrusion width of 0.6 mm. So even every uggly home made printer should make it! With this the design is more failure tolerant.
