Description
Star Trek TOS engineering/security insignia, held in place by two 8mm OD x 2mm rare earth magnets. I use a pair of steel washers inside the shirt to anchor the magnets.
When not being worn, this makes a decent fridge magnet.
There are a pair of 3mm channels on the back in case you want to use a toothpick to poke the magnets back out without destroying the print.
OpenSCAD source files included in case you want to hack at it.
