I just finished the the third version of the design for the front arm. How do you like it?
The goal was to make it stronger and stiffer, while maintaining some of the 'elegance' and sticking with the original length hingepins.
Further info I got from ORB Design but forgot to mention earlier:
The printer type used is not the filament type. Benfits are among others the much higher material density (typically around 98% of the volume), better accuracy and lack of layered structure associated with filament printers.
The material is pure nylon without colorants or other additives. The surface finish is comparable to a fine grain sand paper.
It smudges real easily and is hard to clean. Therefor they offer dyeing (black) at a little extra cost.
Strengthwise: the stiffness is not a the level of moder bugies with glass or graphit reinforced plastics, but it does aid in stress distrubution for endurance. This is what made me review the design, and I hope to have compensated for this to achieve a product that's comparable in performancewith the original yokomo part.
