stake to tie plants to.
extend it by adding printing a another and stacking one on top/inside the other.
stab the pointy end into soil, stack as many as you need for the height of your plant, loosely tie you plant to the stake with string or wire.

in theory, you can also scale in your slicer this based on your needs and as long you keep the scale consistent, they should still stack

Note: tolerance are quite tight on this version. I may add a second version later with looser tolerances, or feel free to tweak to match your printers accuracy
