Rat M.M.O 7 Scroll Wheel

I broke my middle mouse button and Mad Catz doesn't have any replacement parts available so I went to design my own. Surprisingly I was able to and it works! For most printers you will need to print the split file and then use glue, solvent, or epoxy to fuse the halves together.

The scroll isn't perfectly smooth but that's probably because my printer isn't 100% accurate and there are also rough spots. Over time it will probably smooth out.
