Description
This is an adapter to mount two 120mm fans into a single 120mm fan slot in a PC case. The fans are held in place by tight tolerances and friction, with no screws required ( The only screws required are the ones to screw the mount to the case ). There’s a side gap for cable routing, and the design fits standard 120mm fan screw positions.
⚠ Important: You must route the fan cables through the side hole before pressing the fans into place, otherwise, the cables will not fit afterward.
Printed with these settings:
0.32 mm layer height
1 wall
20% infill
You can increase these values if you need a stronger part, but this setup worked for me. The print was slightly flexible, but held the fans firmly in place.
