Based on my earlier model and JiltedGeek's nice mod I have created a supersized version. You can use it loosely or lock them if your tomatoes' growth has not switched to BERSERK mode yet.
The plant clip has a larger, 50 mm diameter, 4 mm wall thickness.
For maximal sturdiness I recommend to print them with 4 perimeter shells with a 0.4 mm nozzle.
The author remixed this model.
This is HUGE :)
