Summary

This is a replacement scroll wheel for the Logitech G604. There are some other ones on the site, but I wanted something as close to the original in design as possible. I got the idea from here: https://rimgo.vern.cc/gallery/GJNjJ5G

Disassembly is a pain, especially removing the scroll wheel from the housing, but it's definitely worth it. No more annoying rattle and extra weight.
