Star Trek Communicator Badge
thingiverse
Star Trek Combadge from the 2370's as seen in the TNG Movies, Voyager, and probably some of DS9 to be honest I haven't gotten around to it yet. Requires four 5x3mm magnets (5mm diameter 3mm depth) and the application of some super glue to keep them in place. Pictures above are painted and sealed, feel free to edit for multi material if you wish.
