The file 'Steelseries Kana V2 Mousewheel 3D Printer Model' is (stl) file type, size is 7.7KB.
I dropped my mouse a few too many times and ended up breaking the rod holding my mousewheel in place.
(To be fair it's only 2mm in diameter and made from molded plastic...)
So I designed a close to identical one for use as a replacement.
