So, I was looking for a simple fumes extractor to use with some extra 120mm fans I had. I really wanted something simple that I didn't have to use screws or glue to assemble. I didn't find what I wanted, but I found inspiration. As you can see, I inspired myself mostly from Hasmar04 and dr.dentz's models.
Even though I used a tolerance of .23mm everywhere, this model is very tight. That's why it clicks when the fan is entered. You might have to force a bit, but once it's there, it won't move. Furthermore, with the enlarged foot, it won't even tumble.
Bring your own filter & Power source! (I used a fan connector to usb wire for mine)
The author remixed this model.
