before or I get too deeply into this project (currently having issues getting my printer to play nice with NinjaFlex) the young boy I'm building this for has no forearm, now I have printed a hand and arm from eNabled and that works great. However he likes the idea of this one having some usable functions in the electronics and us having a play with it, so is there a design for a Forearm to attach the hand to? He has just a small stub after his elbow so it's just the forearm that is needed.
also anyone had any luck getting NinjaFlex working on a Bowden extruder RepRap?
