My boat keys needed a key chain that floats, so I printed this key chain that resembles a marlin in water. It really floats and will keep keys from disappearing into the water, just in case I drop them.

The marlin tail and bill are too fine to hold a key ring, so a more substantial ring is provided.

I had the key chain on a table in a restaurant when a waitess said it was cool and asked if it was carved from wood.
