Bottle Cap Magnet

This is an insert that snaps into a standard beer bottle cap and holds a [1/2" x 1/8" neodymium disc magnet](https://www.apexmagnets.com/magnets/1-2-x-1-8-disc-neodymium-magnet).

The magnet is pressed in from the top after printing, and then the whole carrier should snap securely into a bottle cap (as long as the cap is not too bent or mangled). No additional adhesive should be necessary.
