About this 3D model

Funny nut and bolt fidget toy! The nut moves freely on the bolt and it's such a great toy when designing and thinking. You should print the nut separate from the bolt and select a dense infill for the nut, so it is heavier :) Note that the Idea of this is not mine! But I couldn't find any models to it, so I made it by myself. original idea: https://www.youtube.com/watch?v=cvi8A2XCK94&t=48s
