Update [24-05-2024]: Made the bases of both parts thinner to reduce wasted space in the keychain while preserving strength.
Designed two parts that go into a rectangular key hole to make it compatible with round screws that works with the KeyCarry 3d print.
Might not work for all keys but the "hook" part is relatively small so it should fit most keys.
