This is a plant pot that I use for my houseplants. In the original it is 12cm x 12cm, feel free to adjust the scale.

Settings:

• no support
• wall thickness 3 (2 if you use liquid plastic or think it is enough ;) )
• 15% infill
  

Note:

I recommend PETG as the material. To make sure that the pot is leak-proof over a longer period of time, I coated the inside with liquid plastic.
