I recreate from zero this model taking the idea from an existing one. This one thicker and it is made for pegboard with 37.5 mm distance beetwen holes. No support required.
I find it better than the usual one with just a hole cause this can accomodate basically every type and every brand of screwdriver, and most of all you don't need to have clearance at the top to extract the screwdriver, but you can lift just a bit and pull straight away thanks to the cut in the front.
You'll find a .stp file if you want redesign by yourself.
Bye!
