IKEA Korken Stacking Adapter

thingiverse

This adapter lets you stack two IKEA Korken jars, either the 0.5l size or the 1l size. Other sizes won't fit because their rounding is different. I wanted to put two of these in a drawer but they kept falling over. This stacking adapter solves that problem. You can print it without support, with the rounded part facing the build plate as shown in the picture. You could also move the part 1cm under the build surface to print less of the holder for the upper glass. The current height is 2.5cm, but a little bit less will work just fine.
