Ventilation on mini greenhouse

Hello,

this valve is made by me and can helps to air circulation in minigreenhouses. When your seeds are still not over the ground you need to close valves and keep high humidity. As soon as seeds sproud up you should open ventils a little to bring up some fresh air into greenhouse.

I print that thing with PLA with 20% infill. Printing speed was 60mm/s on Creality Ender 3 v2.

It is a simple assembly. You can follow the image.
