The first print of the original model had some weak points, which I have improved in this modification. The changes are all done in PrusaSlicer and I only uploaded the PrusaSlicer project which contains all parts and modifiers. For those who do not work with PrusaSlicer, the changes may not be usable, so the modified parts - rotary handle and egg holder - are attached again as STL.The two basic parts (mainmount and movablemount) have been adopted without modification. As the fit of the ball bearing in the holder was also a little wobbly, I fixed it in the recess with a small 1 mm nail.
