I needed a support trellis for climbing plants in a pot or planter, and came up with this.

The design exploits the build height of the Bambu Lab A1, the print height is 252.5mm.

• X1 and P1P users: You need to do some tinkering to print higher than 250 mm.
  Alternatively, just scale the model slightly down in z-axis. 99% should be enough. 
• A1 mini: Sorry, this model is too high for your printer.

New sections can be added to the top when the plant grows.

The pins that hold it in the dirt are press fit, no glue needed.

Vertical sections must be glued together, see illustration. I use super glue (cyanoacrylate).

It is a long print due to a lot of movement and little actual printing: 11 hours with 0,4 nozzle and standard build quality.

No support needed.
