Seed Phrase Holder

thingiverse

A simple holder for sensitive documents like seed phrases. Its a box with a cavity in the middle and an angled inset slot to feed the document into. Pushing the document into the slot all the way will cause it to drop into the cavity in the box. This design makes it almost impossible for the card to be taken out without breaking the entire case. This does not on its own provide security for seed phrases but does help with both obfuscation and provides a good means to determine if its been tampered with. Note: Some low infill print may be see through. Just be sure to check that its not before using these. I recommend customizing this print with only a design you have to avoid others making direct copies and playing it off as yours
