My 1 y/o kids (twins) broke the mouse wheel, so I've designed and printed the full copy replacement. Was printed on Ender 3 V2 by Creality, it's my first 3d printer, which I own a month. And my first thing that I've designed. Used 0.2 mm nozzle, 0.1 mm layer thick, 25% infill, supports needed. If you will Print it vertically a little hexagon (1.7 mm in diameter) may broke easier. It is better to print it horizontally.
