Its really cool!
People have been telling me none stop that PLA will never work for this...
The wear is actually so minimal that I haven't needed to grease the moving parts more than once--After hours of drive time, there is almost no wear on the gears--The only thing that wears are the dogbones, but that is because sand and dirt get into the joint and cause wear, but they still last much longer than you'd ever guess.
What are your thoughts?
