Window mount for 120mm Fan (for 3D ABS fume extraction) Updated to Version 2

The 120mm Fan mount will hook into a sliding window. For my installation I have used a published 120mm air ducting adapter ( http://www.thingiverse.com/thing:2001198 ) on the other side of the fan to run ducting to my 3d Printer. With the fan at the window end there should be negative pressure throughout the ducting to minimise smell leakage.

Update 18 Feb 2026 (will also be loaded on Printables.com)

Design cleaned up with 2 options
- Thread insert version 4mm thread, 4mm deep
- 3.3 mm hole
