IKEA Korken Stacking Adapter

This adapter allows you to stack two [IKEA Korken jars (0.5l)](https://www.ikea.com/de/de/p/korken-dose-mit-deckel-klarglas-70213545/) or [IKEA Korken jars (1l)](https://www.ikea.com/de/de/p/korken-dose-mit-deckel-klarglas-50213546/). Other sizes have different rounding and will not fit!

I waned to stack two of those in a drawer but they always fell over. This stacking adapter fixes the issue.

Print without support. The rounded part is facing the build plate as shown in the image. You can move the part e.g. 1cm under the build surface to print less of the holder for the upper glass. It's currently 2.5cm but not that much is really required :)
