A simple holder for a Trezor Model T hardware wallet, that is compatible with the Gridfinity modular storage system.

The wallet sits primarily above the base of the storage block, with an indent at the bottom to hold it in place, and a slanted back at an angle for stability, and for looks.

If your printer has any trouble printing the base accurately, I would highly recommend slowing down your printer to half speed for the first few layers, as this helps significantly with adhesion. Adjust the speed as needed depending on how well it sticks to your print bed.
