IKEA KALLAX drawer inserts

Other IKEA KALLAX drawer inserts I found online where either too thick or too thin and they were all missing the configurations I wanted, so I designed my own. These boxes in particular have triangles on each corner to help them slide when they are stacked on top of each other. Every wall has a thickness of 1 mm.
