I needed a sleeve to cover the cheap, nasty pots that often come with carnivorous plants, but which would still allow the inner pot to sit in a saucer of water to soak up through the bottom of the pot for bog plants. This sleeve sits around the plastic pot, but doesn't cover the bottom. It's very much an early draft and I may come back to it to try to taper it somewhat!

No support needed, although I did use a brim for my print. No idea if it's needed though, and imagine it might not be.
