I've always had a thing for converting Pickle jars into homemade terrariums. Along with other glass jars.This is the next level.

The bottle that this part is set up for a "Oui" Yogurt container. I found them at my local Safeway here in the SF bay-area. Your availability may vary.

It's a simply pressure fit. Poisson the bottle and push down.. I would suggest 5-6 walls for the roof to keep it from leaking. And, if you use cura, the iron top setting works wonders.

Ive included the Soildworks 2018 file for your modification as you wish.

note that the black feet you're seeing will be uploaded if there is any interest.
