Magnetic Tool Bracket

A magnetic tool bracket designed to hold 3D printer tools. Has 4 slots on the base for magnets with dimensions Lx 20mm Wx 10mm Hx 1mm.
There are 4 screw holes, 3.2mm wide for the option of screwing to a wall, bench etc.

This is just a prototype, I have NOT printed yet, but plan to in the coming days.
The dimensions for the magnets are taken from the following website:
