/Boxes/EpoxyResinBox.foocad

A case for two-part Epoxy resin. I buy the cheapest, which comes in two tubes, and minimal packaging, so I need somewhere to keep the two tubes safe from damage, and without touching each other.

Print Notes

Print the hinge using flexile filament, and simply glue it to both halves.
