Makes any object wall mountable! File is intended to be 'cut out' of another 3d model to create a hole that will allows for drop-in wall mounting. Use the provided DWG in your favorite cad program to 'solid subtract' this model out of a thing you want to mount on a wall- it will create a hole that a drywall screw will fit in and drop down onto, gravity locking the thing in place on the wall. The drywall screws should be screwed into the wall with 3/16" distance from the front of the head to the wall. I usually print this with .2mm layers and at least 3 shells. Bam. Wall mounted things.
