Printed Stacking box by CreativeTools and had some warping with PETG in vase mode, so I flattened the sides to see if that would improve it. The modification only marginally improved the print, so I’m sticking with the original, but I wanted to upload it anyway in case somebody wanted it.

It is the same dimensions as the Stacking box so they will fit together, but it weighs about 1 or 2 grams less.

Print in vase mode.
