There are not that many rectangular planters with drainage holes available, so I created my own.

The pattern on the sides of the pot is based on the aperiodic monotile called the hat. If you are interested, take a look at this model or this one.

The non-repeating pattern made it difficult to model it, and the construction was quite complicated.

These videos helped with construction:

I attached the step file of the pattern itself. Note: I messed up the pattern somewhere, which is why there are some gaps.

Printing

For printing, I strongly recommend a brim for both parts.

I printed mine on the P1S (print settings are in the 3mf, just open it as a project with OrcaSlicer).

The bottom uses about 100g of filament and the top part ~300g (~400g in total) and took me ~10 hours to print with a 0.6mm nozzle.

The model should not be printed in vase mode, and it does not require any supports.
