Mini greenhouse using Ikea Morgontidig bell cloche to Gradvis flower pot adapter

Uses an Ikea bell cloche (Morgontidig), to stack on a Gradvis plant pot. It's great for keeping the cats away when growing catnip indoors.

Ikea made 2 cloche sizes, this print uses the larger of the two. Both sizes have been discontinued. Looking closely at the cloche, it's not completely symmetrical, it's almost an imperceptible oval. I think the manufacturing tolerances were pretty loose to begin with. Since the groove the cloche sits in is wider to accommodate the loose tolerances, you may notice the asymmetry when viewed from above.

This was designed for the 4 3/4" Gradvis plant pot. The tolerances on these are fairly consistent, so the fit is better on the pot side.

I've included the f3d file if you want to adjust for other pot sizes or tolerances. 

UPDATE: After a few uses, you may find mold/mildew growth on the connecter ring due to high humidity in the dome. Realistically, this is an over complicated solution to a minor problem. I recommend getting a hanging planter that the cats cant reach and growing your catnip there.
