We have a vanilla plant that started young and then grew large. 

To accomodate this, I designed a plant guider/trellis that consists of a base that fits a regular sized pot. Stackable elements can be mounted on top depending on the growth/size of the plant.

See photos of the current size.

Filament: For outside use PETG. For inside/room temperature, PLA is fine, however, some people struggled with some PLA brands reporting that the structure might easily break. So I suggest PETG from now on.

Reference: Regardless, we used PLA, and the plant lives at the window, gets lots of sun and it's totally fine.
