40mm Fan Duct

Printed this housing for a 40mm fan. Found this USB powered fan from a ¥100 shop in tokyo and thought it would be fun to house it properly. The funnel at the intake and the cone at the outlet does make a significant difference in the output of the fan as well as makes it quieter.

Needs 4 x 16mm Cap Screws to join the two halves. Included 2 x 2.5mm holes below next to the wire outlet spaced 10mm apart so you can design your own mount.
