I mounted mine to the side of my garage cabinet, and I only had 1 hole to use! Remixed from model from User named Bukken.
10mm through hole, and can be reached through the hex pattern.
I printed white to match my garage cabinet too… :-)
I included the .step file, so someone could import into a CAD software and add more/different holes for their application!
The author remixed this model.
Added back plate and through hole that allows mounting with a single bolt.
