My sister asked me to make her couple of planters for her new office. I couldn't find a suitable model (she was rather specific), so I created it in 10 minutes in tinkercad. Still printing as I'm writing this. Designed to be printed in PETG, with 4-5 wall loops and 5+ bottom layers, to obtain at least some waterproofing.

Added 6 and 7 sided version.
