Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4403057.

modular support system to help seedlings grow without falling over (e.g. sunflowers which grow fast and fragile)

print the base once per plant, then print however many segment pieces you need (start with none, then add one at a time as the plant grows). they are designed to slide onto one another (20mm overlap).

designed to support 0.8mm nozzles (should work on anything smaller as well).
