About this 3D model
Small key hook magnet. Uses two (2) Harbor Freight magnets (5/16" Diameter; 5/64" Thick). My magnets were a press fit, but a drop of cyanoacrylate glue (Super Glue) can be used if needed. Depending on your magnets, printer, and settings, the holes may need a little finessing with an X-Acto knife.
