This is a simple hermetic square box with japanese pattern, that was made to fit the other boxes I made (here: https://www.thingiverse.com/thing:3391662 and there: https://www.thingiverse.com/thing:3400910)
The top should be printed upside down, but it might be tricky to get the full depth of the pattern depending on the precision of your printer or if you have a heated bed. So I added a flat and filled version to print right side up in case you don't have a heated bed or you want to keep full details on the top of the box (but you'll lose the space in the lid).
The print can be very tricky.
As I don't have a heated bed, the first layers are really curved which kind of break the effect of this very geometrical box, but it stills work.
There are two versions of the lid: one is filled and can be printed right side up if you want to keep all the details on the top of the box, but you'll lose the space inside. The other makes the box bigger but the result will depend on how good your printer is with first layers (mine wasn't that much...)
