Magnetic hydrometer holder

I needed a moisture meter holder with a magnet for my safe.I created this simple model.To complete it you will need:1x M4 x 10 socket head screw1x 16 mm diameter magnetic hookI really liked these hooks for my constructions. They are very strong, have an M4 mounting thread and the magnet is protected against impact.You need to unscrew the hook from the magnet and replace it with the M4 screw.The model has a solid support modeled in place of the screw, which must be removed before assembly.
