For mounting a rectangular electromagnet, at an angle, to a variety of things. Like hanging it from a strap, or mounting to a piece of wood. So you can secure something else to the metal contact plate that it holds, when energized.

Provides a raised lip to align the metal plate also, this keeps the plate from sliding off the sides, for maximum holding power.

You will need to glue the magnet into place, I used a few drops of superglue in the corners.

This is for the commonly sold rectangular “door holder” electromagnets, 80mm x 38mm ( 3-1/8 x 1-1/2 inches). See picture for what I bought from Amazon. Remove the right-angle bracket that it comes with (not used for this print) you’ll need to remove it by removing the two black screws (Torx head).

Print in PETG for best strength, but PLA can work if you are careful. Must print with suppports to get the correct orientation for strength.

Edit for v7: I have modified the side cable cutout smaller, to prevent weakening the structure on that side.
