"Pebbles" for planting
thingiverse
Artificial pebbles for planting. Can be used instead of the clay pebbles. Diameter 9mm, but in slicer you can play with scale to produce required diameter or make oval pebbles. For cost reducing, infill density 0% can be used. Also I had good results with wall thickness 2 lines (~0.8mm). The bottom of pebbles is slightly flat and brims are not required.
