A quick and dirty remix of a Multiboard 9 mm Small Thread, Flat Head, Bolt, where I added a parametric hole in the center for a 6x3mm round magnet.

Print using standard Multiboard/MultiBuild settings without supports. Note that I designed the magnet pocket with a somewhat loose fit, for the magnet to be superglued into place.
