Based on the original idea of an easy to print but still quite sturdy stand for test tubes I designed a round variant.
It holds up to 10 tubes, is stackable and you will need just short of 40 m filament for one print. Fits Tubes with a diameter smaller 18 mm.
This piece fits well to my other parts for my fully printable lab. Check them out:

Loved the idea and the easy to print approach of a sturdy stand for some test tubes. Changed the geometry to a round one.
