Worried about your keys while you're out on the water?
No need with these key buoys. They come in three different sizes to keep a variety of key chains afloat.

Size M:   1 key
Size L:    2 - 3 keys
Size XL:  4 - 5 keys
 

The number of keys is only tested with my own keychain, please feel free to comment how much weight you could keep floating.

Print instructions:

• Print in standing position
• No supports on the inside of the buoy
• Solid walls to keep the buoy watertight
