Magnetic Locking Quick Key Release

thingiverse

Magnetic quick release keychain uses 8x3mm magnets. May require some scaling on the parts to get them to fit perfectly on your machine, however, I designed the part to allow some tolerance between printers. If you don't have magnets it still works without them. Only requires supports for the little nub coming out of one of the parts if you don't want it to be slightly droopy.
