This is a rounded stem for the Lego flower pot model called “Lego Inspired Flowers” by user 365Prints. I made this because I wanted my flower arrangements to have many flowers. Unfortunately, the original straight stems are not stackable. But with this model, you can add as many rounded stems at the base of the pot plus up to two straight-stem bricks at the top.
Please, refer to

to get the original flowers, the flower pot, and the straight stems. I am only providing these files for convenience.
I printed the pot in Prusament PETG Terracotta and the stems in Prusament PETG Jungle Green and Prusament PETG Pistachio.
