Open Hardware Fidget

prusaprinters

I created this a while a go, but forgot about publishing it. Then the Prusa MINI got the input shaper alpha firmware and that reminded me about the nature of the Prusa machines being open and that made me want to try printing the model and publishing it. It's a fun model to fidget with. I made all the calculations so that all parts can rotate freely without touching. The middle ring can spin freely. Initially the rotation might be a bit locked up, it will take some fidgeting to get it loose. I recommend letting the part cool completely before trying to get it loose, otherwise it might still be soft and the shafts will twist. Painting the seams is advised. Otherwise it might bind. You can use the 3mf project or paint them yourselves. It should look like this:I've attached the Fusion 360 file for potential remixing, have fun!
