I created a zip tie edition so that the zip ties do not only close the rooting ball, but also hold the ball on the correct spot on the plant (at least that is the theory ;) ), the branch has to be only big enough, means more than 7mm I guess. Furthermore also the sides can be closed with zip ties
Supports should not be needed, rafts depends on your printer.
Else the guide from the original is still valid:
The ball works for branches up to 20mm, segments of the grid can be removed as needed.
PlantRootingBall_2x has to be printed 2x,
PlantRootingBall_Clamps_4x has to be printed 4x
Resolution 0.2mm, Material PLA
How to use:
Done.
The author remixed this model.
