Basic fan mount adaptor to downsize a 50mm fan to a 40mm fitting.

Mount holes may not be precise and may need drilling slightly, but they should be OK for their purpose.

EDIT – Updated file added, bolts were too close on old design. Bear in mind this new design will need supports or a fan to print properly.


Made in Sketchup and exported as STL.

Tested with Slic3r and Kisslicer.
