Dummy RCM print

The first print was a disaster! Or, at least, my aggressive "cleaning" of the part:

I was "aggressive" in printing this part on a few points:
  • I aggressively hollowed out the interior of the mechanics (I am interested in hollow robots and joints in general), and ended up making the shells 1.8 mm thick. In addition, I removed a lot of material from the joints, which made a very weak connection point. (Actually, all breakage points are at this location.)
  • I was too eager to see the assembly move, and yanked hard on the model before the wax was completely removed. It was then too late.
A second iteration is queued for printing, with adjustments to the design to reduce the fragility of the joints.
