Collar Flange for Self-Watering planter

I have printed a few of the fantastic self-watering planters. One of these has my venus flytrap in and it was getting very large, with the traps spilling over the side of the planter.



To try to keep the traps vertical, I have produced this collar which fits over the top of the pot to provide a flange for the traps to rest on.
