This is a mount for a Bosch 12v Multitool, designed to be mounted to a 1" x 1" peg board.

Supports are only needed in the mount plate and the inner arch. 

Uses Sy's pegboard mounting system. These universal mounts solve a lot of the pains that pegboard prints have. It makes the pegs in a way that isn't brittle, and if it breaks you don't have the replace the full print, and it secures the mount better while being easier to get on and off.
