30mm to 40mm Adapter for Fan

thingiverse

This print is designed to accommodate a 40 mm fan, replacing one that was previously 30 mm in size. To use it effectively, you will need M3 screws that extend through your fan mounting holes and leave an additional 2mm of length for secure screwing into the print. The holes for the 40mm fan are precision-cut to allow for seamless threading of the M3 screws. In contrast, the holes for the 30 mm hole pattern are slightly larger to facilitate easy mounting.
