PowerSpec 3D Pro/FlashForge Creator Pro Screwless (ABS and Acetone) 40x20mm Fan Duct

This is a remix of my original active cooling fan design. The original design is still in use and has been used continuously for the past 2 years.

This design replaces the fan bracket with one where the fan slides in from the top to be held securely.

Note: this design is for a 40x40x20mm fan, where the original design was for a 40x40x10mm fan.
