2 Part Magnetic Keychain
thingiverse
We have a fob that must be tapped to enter our parking garage, which means that it couldn't be kept on the same keychain as the car keys. With this magnetic keychain, they fob can be detached and reattached easily to the main keychain. Uses 4 8X3mm magnets, two on each side. Once superglued into the holes, they don't move. They give a nice strong connection, with no fears that it will detach unintentionally. Print as fine as you can as tolerances are tight. You may need to wear it in a bit to get it to connect smoothly every time.
