This is a replacement scroll wheel for the Corsair Scimitar series of mice (should fit the Scimitar Pro RGB, Scimitar Elite, and possibly others).
For more details (including print and post-processing instructions), please refer to the article on my website here: https://www.willsthings.com/articles/2021-7-13/fixing-a-broken-scroll-wheel-corsair-scimitar-pro-rgb
Some features are slightly oversized to ensure compatibility with most SLA printers; You may need to do some slight trimming with an Xacto knife, or (wet!) sanding to get a proper smooth fit in your mouse. Be sure to test fit and sand / carve if needed before post-curing!
