An Acetone Vapor Chamber. This is a work in progress. I will get back to it if there is a popular response.
This is meant for glassware you can get at any hobby store, like Micheal's, Hobby Lobby, Joann's etc. The larger one is the 12" fishbowl and the other is the 8" cylinder vase. All these retail places seem to be selling the Libbey Glass company product.
The black section may be scaled as much as you want to make it as tall as you want.
The top portion fits a 100mm cutout and is the same for both sizes and the 12" bowl version will use the same base design as the 8" version. The fan vent can rotate for you to set the desired circulation pattern.
