Super73 Keychain
thingiverse
I'm a huge fan of Super73 and created a custom keychain for my bike's battery key, turning out fantastic. To get it just right, I recommend giving it a gentle sanding, applying some primer, and finishing with a coat or two of spray paint if you're particular about the finish.
