Make a USB drive keyring

My first sugru mod (hence the fingerprints): a pack of sugru applied on the naked PCB of a USB flash drive with an attached key ring creates the perfect USB flash drive for your keychain (because most USB flash drives currently lack a decent ring). It's cheap, it works, it wins. sugru, ftw!

Bonus: you can use a marker to put your phone number on it (in case it gets lost).
