Magnet Sharpie Cap
thingiverse
Wanted a sharpie cap with a magnet cap to put one in my workroom and one on my fridge. Designed it then realized V1 was a touch..... phallic. So made V2 which I'm much happier with. Freecad files attached for both versions. Magnet size: 12mm x 4mm or something that fits in there. Freecad file should be adjustable for whatever size you have.
