A multicolor keychain I made, a nice simple design but it pops nicely.
It was not designed to fit in a pocket so I would recommend scaling it down if that is your goal.
The colors were not chosen for any reason other than that they were the ones I already had in the AMS, please upload a print profile if you come up with something better.
