Yet another fume extractor. Made this to use up what I had lying around already. 

Uses a 120mm pc fan, usb c pd board, pwm fan controller, and a 130mm filter.

Assembly Instructions:

1. Press m3 heatset inserts in the 4 corner slots
2. Screw pc fan into ‘FanHousing’ using pc fan screws
3. Install fan controller through hole in the side, and screw it down with included nut
4. Hot glue USB C pd board through back hole
5. Filter just gets press fit into the ‘FilterHousing’ Part
6. screw it together using m3 screws. 

BOM:

• 4 m3 heat set inserts
• 4 m3 screws. I used m3x8, but a little shorter or longer would work. 
• 120mm pc fan plus fan screws (Higher airflow the better, but whatever you got will work)
• USB C PD Board.
