The file '40mm Terrairum Fan 3D Printer Model' is (stl) file type, size is 28.7KB.
I needed a fan to exhaust my small terrarium to keep the glass from fogging up.
You just need a 40mm fan, a 40mm hole, and some M3 coarse screws.
I used a 12V fan on 5Vusb so it doesn't exhaust too much, and put it on a timer for when I'm awake.
