after the mouse wheel broke i looked to see if anyone else had a replacement and checked their dimensions and no, no one did the internals of this mouse have a smaller hole for the clickwheels to register. so i made my own that fit, printed one out of abs and it works well. print with supports rotated 90 deg for best results

included is a stl and a fusion file so you can edit it inside of fusion if it needs tweaking for your mouse

confirmed mouse it works with is the arteck model MW16
