3d Printed PMM custom shell. This custom print is very old, from back when PMM was one guy making 3d STL files for you to purchase and make yourself from scratch. It's based off the Zowie S2 shape.
Was printed by my friend, and put together by me. It's in very good shape, the print feels incredibly nice and sturdy. The mouse clicks are perfect. Everything about this mouse is pretty awesome. Uses a AAA battery for power, which you will need to replace with a rechargeable one eventually. It has a hole specifically for that purpose.
The mouse feels and looks great, and is a great look into the history of PMM and of mice in general. This was one of the first 'ultralight' designs available.
Only con is the mouseskates are slightly misaligned, so it wobbles a tiny bit. Will go away with use, or you can replace with better skates.
