Box Stacking Corners

I wanted to use the original Gravitrax boxes - including the lids - for storage.
For this, I designed parts, that can be put on each corner of a box / lid, serving as a platform for stacking another box/lid on top.

These coreners can be used for any type of boxes, e. g. from board games or puzzles.

There are three “Stacking Corner” files for different cardboard thicknesses (2.0, 2.2, 2.5mm) - if you need another variant, please contact me.

The brackets, that keep the upper box in place, have to be connected to the corner with a drop of ca glue, as my goal was to allow for printing without supports.

There are two brackets - one for lids (larger edge), that need to fit upside down on a box - and one for boxes (shorter edge), that need to fit on a lid.
