I was making a set of hand models to go on a pegboard, and while I ended up making a solid object with pegboard pegs and the hands, halfway through I realized the mounting design I had made (and discarded for the hand project) would work for mounting any 3D Design to a pegboard.

The pegboard mount works with the hands, so it should work with the model in this design. Add the plug to your design and 3D print your modified design. The plug slides into the pegboard mount.

Ideally you should print the pegboard mount in its upright position with supports. This seems to make the plug mount in the front and the pegs in the back print as sturdily as possible.
