A FUSION360 file is attached. The pot was made for personal use so the FUSION360 file is not perfect. I have translated the PARAMETERS to English to make it easier.
The STL model is adapted for use with a toilet paper core of 38mm, to help hold the soil in place. But it can of course also be used with rock wool or similar.
The part in FUSION360 named "3D" is only to show how it will look in folded condition.
