Magnetic hook

A simple hook that can contain a magnet up to 22.5mm x 18.5mm.

There are two versions. One is open so you can glue in a magnet after printing. The other is closed so you need to pause your print and add the magnet right before the layer that will cover it. The closed version can take a magnet up to 2.5mm thick, while the open one can pretty much handle one as thick as you like. The open one tends to stick better, since the magnet can be right against the surface, but I like the closed one
