Backup Bin with Seal

A hexagon shaped, screwable Stackbox for a Blockmit style Seed phrase backup using M8 stainless steel washers (24 mm outer diameter). The container screws shut safely and can be locked with a tamper-evident seal (included) through the two slits on the top and bottom. To open it, the pictured seal, the container itself, or both must be damaged or destroyed, which will be evidently visible.

Space wise, it perfectly fits 24 M8 steel washers locked on an M8 55mm bolt with locking nut. 3D-printed from biodegradable PLA.
