Remix of a remix of RT3D's Wire Cutter Wall Mount to have a generic hook attached to a Lack enclosure.
Print with supports (as shown in the images), remove the supports and then gently push on the plexiglass from the inside of the enclosure and slip on top. There should be enough clearance that it should easily move forwards/backwards (or side to side)
OpenSCAD file provided for anybody that wants to play around with this. There is one customizable/Customizer setting - the size of the arm (how far it sticks out).
