The 3D printed parts arrived yesterday – they came out amazing – and I spent some of the afternoon assembling them into the final skeleton. All the magnets fit really well. I do wish the holes for the screws were threaded, but for now I just gooped super-glue gel in all the holes and hope it all stays together.
After having an almost completed skeleton model, I can now see where the weak points are, and the biggest one is the spine. The large magnets just can’t support the weight of the upper body very well. The arms hold pretty well, I’d say 85% throughout the full range of motion. So for now I need to focus on redesigning the spine. And I still have to figure out how to attach the fingers to the hands. But other than all that, the model is super cool!
