Rugged Fume Extractor for 120mm fan

thingiverse

My design incorporates sneakypoo's head filter with a wider base that serves as a convenient tray. A compact box is currently in development to fit snugly on this tray, permitting the operation of a 12/24V fan at its nominal voltage via USB power. This upgrade will be uploaded shortly. Update: October 11, 2018 A revised version 2 of the fan mount and stand has been uploaded, featuring smaller holes with a diameter of 2mm.
