The attached photo was because of my mistakes. Many pieces printed like so. Regardless of my carelessness it's so well designed it holds together and works. One thing that could maybe help is making the end of the crank arm empty - that would first of all reinforce the join point with more sticky point and allow us to insert metal / proper support there. The only thing that was somewhat off for me (but again , since my plate was off on Z axis it could have been on others as well) were some of the screw wholes. In all honesty I think all the issues were because of how I organized the plates to print "faster". All in all a model, fun to build and very loud! I will try scaling it down a bit at some point, need to find proper bearings for it first :)

Needed some understanding and specific holder to use with my phone. Small hold seems to small, big is too big. Mind you I printed in PLA only so the phone case is not very flexible. I am using iPhone 13 mini. Would be good to have adjustable screw lengths easily available. The locking was too short for my desk - admittedly it's very thing (probably the stl is there I just didn't pay attention)
