Trezor Case for Trezor Safe 3

I chose a generic hinge case as the basis for the model as it's dimensions closely matched that of the Trezor device. I unfortunately didn't bookmark that file but if I do find it again I'll link that base case here. Dimensions have been altered slightly and cable clips added to the lid to secure the Trezor data cable.

A Trezor Safe 3 insert has been generated which is a snug holder of the Trezor 3 so retains the unit even inverted but it is not an overly tight fit so it is an easy task to remove the TS3.  The insert is deliberately a tight fit into the case so there is no possibility of removal once inserted without heavily marking or completely destroying the case and insert. This means coded information can be 3D printed onto the lower case inside face or the insert lower face to aid access or wallet recovery which could be useful particularly to any family member inheriting a wallet.

The case is 3D printed in lower and upper sections and snap together with a fair bit of upward and downwards coupling force. You won't get them to mate from the side, one body hinge needs to be snapped down onto and into the other. The coupled hinge provides decent friction so stays where it is opened.

I printed my case on a textured plate, it can be printed on a smooth plate if a smooth base and lid finish is preferred. Parameters for a PLA print were 0.1mm layer and no supports. I have added text to my own storage case upper face on the insert to identify which TS3 device has been allocated to the particular box.

The choice of filament may improve the model. The clips can be snapped in PLA if you get too forceful feeding the cable wire through and into the clip. Possibly a PETG print would improve the flexibility but I only have PLA available so that is what I used.
