This vase is one of a number of vases I've created to hold test tubes in which cut flowers or live plants are kept. It is designed around a 25mm diameter test tube that is 200mm tall.
See here (Amazon link) for the exact (decorative) test tubes I use.
It prints very well with default PLA settings with a 0.6mm nozzle at 0.3mm QUALITY settings. Looks great in Prusament Mystic Brown PLA.
Note: this vase is #6 of a 9th set, most of which aren't really worth sharing, but a few others are. I'll be posting those at a later date.
The author marked this model as their own original creation.
