Thank you for this model! It is nice and easy to color on the outside, but the overhang on the inside leads to a printing problems without supports and seems unnecessary to me. I was surprised, that it stuck to the bed well with the little amount of surface.
I am working on a solution to keep them from not unscrewing. I am going to put a bearing in the window handle. https://a.co/d/aDZY4Xy these should fit. I am also thinking about putting a threaded insert in them and using loctight to ensure the screw wont come out.
