GT2 Sleeve for 625zz Bearing

This is designed to fit over a 625zz idler bearing for X/Y axes. It is for GT2 6mm wide x 2mm pitch belts (standard for consumer printers).
When twisting your belts isn't an option, and you don't like the toothed side running over a smooth idler, this is a quick and easy solution.

Update: Included sleeve for 608 bearing at request of user.

Enjoy!
