Interior dimensions: 50mm x 75mm
Inner fillet radius: 8mm
IF YOU JUST WANT TO PRINT IT, USE box.stl DO NOT PRINT HALVES SEPARATELY!
Material: PLA, PETG, ABS, really any material should work. There is enough clearance in the hinge to prevent it from getting stuck.
Uses about 68g of filament.
Layer height: 0.2mm
Wall loops: 2
Supports: No
Infill: 20%
Printed as-is, the box can support at least 100kg when closed without cracking.

However the original design did not print well in PLA for me and the clasp was very difficult to open. I redesigned this in OnShape. I also made the clasp hidden when closed, and added small handles to aid in opening.
To modify parameters, you have to use OnShape. Just change the variables in the model, then export the assembly: https://cad.onshape.com/documents/e1946af74b3ec519cf95aeaa/w/773e59c374bfef063256e68b/e/5d6981fdadbdc7ff73359050
The author marked this model as their own original creation.
