There are 2 versions of the box, one with 0.8mm walls (2 perimeters - 0.4 nozzle) and another with 1.6mm walls (4 perimeters). Each one has lids with different gaps (0.15mm and 0.2mm).
If you need a box that doesn't open easily, print the thicker one, with the smallest gap. The lock will work better with that version too.
Tip: keep the most used things in the first sections, so you don't need to slide it all the way out to get them.
The author marked this model as their own original creation.
