Hey, fellow Shapeways enthusiasts, For kicks, I'm trying to work on a mini-figure model that would be compatible with Hasbro's Kre-o line. The parts I've designed are mostly complete, but I'm having a little anxiety about the ball joints on the shoulders and hips. Has anyone here worked with similar joints? I've intersected the spheres from the limbs and created little ports on the way to the hollowed out socket, but I'm not sure how wide a path I need to clear so that the joint can be pushed into place. I'm also trying to figure out if I should slope the pathway in one direction or another (like a ramp leading to the hollowed socket). I hope that makes sense...I'm still just learning how to speak in 3D. Any recommendations are much appreciated! Thanks! T.
