Safe Deposit Box Envelope or Keepsake Box

This is a sturdy thick box can fit DIN A4 (⅓) paper that is folded in three, or envelopes that fits them (DL-size), or other mementos. The inner dimensions has gotten some extra wiggle room to get envelopes out easily. Paper envelopes are usually standard sizes, but a too tight fit will ensure a hassle when you want to get them out. Outer dimensions39 x 233 x 123 (H x W x D) Inner dimensions:30 x 225 x 120 mm (H x W x D)Printing instructions and notes:I used PLA black. I prefer non-matte, as a matte filament is softer and will discolor with a bit of frictionYou can print the whole box on one plate, but that's pushing it. I used two plates to make the best print possible. I included a bit of space around the closing mechanism. However, the first few times opening and closing, the lid will be a little tight. Adding more space makes it a too loose fit. I could've used magnets as a mechanism, however, I put harddrives in my safe deposit box, so that wasn't an option. Design bac
