Buoy Keychain

Add this to your key chain (no electronic keys, obviously!) to have them float if you drop them in the water.  

I tested it on 2 regular house keys and it was able to keep them afloat in a cup of water (see image).

The majority of the print has 5% infill, where the eyehook is there is 100% infill for weight and support purposes. You can use a modifier to change the infill amount, or download the .3mf/gcode which already have the infill modified as described. The model in the image I printed without supports but it got a little gummy around the lip, so I added supports for the files attached here. 

Im sure people can get creative with multiple colors (I haven't set up my MMU2S yet) or imagery on the sides. 

Enjoy! If people like it I have some ideas for an upgrade that could let it handle more keys.
