Survival Bobber Keychain/Boat Key Float

thingiverse

This is a double design. It can be used as a float for a boat key and stuff for survival can be stored inside, or it can be a survival keychain where the thing acts as a bobber and a storage container. Fill with scalpel blade, fishing line, hooks, a couple lures, matches, water purification tablets and you are ready to go. Or fill it with whatever you like. May need to print at 100% fill or add O ring to make it waterproof
