I have my ender3 in the Creality Enclosure and I needed an exhaust system to push the nasty fumes out of my home.
This design includes and exhaust using a 12v desktop fan controlled by a RaspberryPi ZeroW. The fans receives orders through HTTP requests. I have created special Octopi G-Codes to turn the fan on and off, so that the fans starts when I start a print and stop when its done.
The arms are pressure fitted on the enclosure.
It's designed to fit a 3in flexible pipe.
The author marked this model as their own original creation.
