I got tired of losing my Trezor on the flimsy lanyard they supply you. So I made a case that not only protects the Trezor but has a beefy key-ring attaching point. Support material will be a pain in the arse, when removing from the inside. Can be printed flat, but more support material will fill the inner cavity completely. When finish, insert the Trezor at the LCD port, then use a non marring tool to work the flex case around the top of the Trezor. Enjoy! Any donations greatly appreciated.
