Credit Card Jet-Ski Key

thingiverse

This is a safety key for your jet-ski that will fit in your wallet. It is 1.5mm thick, so it is a little bulky in your wallet, but it will fit. When you are done printing, you just put in your wallet and save it for a rainy day when your jet-ski safety key is lost, and you don't want to delay your fun time by 20 minutes printing out, or buying a replacement. I would recommend that when in use that you attach a string to the hole in the key and tie a slip knot on the other end for your arm so that the key will still serve its purpose as a safety measure. I tested this on my Waverunner, and it lifts up the disk more than enough for the Jet-Ski to work.
