This is a plant propagation test tube holder made for the IKEA skadis, it fits 16mm test tubes but they require a rim on the top of the tube so that it can hold.
I don't suggest that you resize it because the hook that attaches to the skadis grid may not fit in anymore and the test tube slides in pretty good even without modifications
I used supports and I did not flip it or anything.
infill: 10%
supports: yes
brim: yes
Printer used: Anycubic Kobra 2 Max
