This door is really cute. But more important it is easy to assemble and add to the dome. It has space around the door to allow the hot air from drying the granules to escape but block the granules from being ejected by the kicking. Now if I could just explain all this so that Nefret understood, everything would be great. She won't use the Genie with the door on. I'm working on her. Hopefully in the near future.
