QUIET 40mm Axial Fan adapter - instead of 5015 Blower Fan

thingiverse

This design allows a quiet 40mm axial fan (eg. Noctura NF-A4x20) to REPLACE a noiser 5015 blower fan. It converts from the vertical box connection which would normally accept a 5015 blower to the circular mount with four mounting holes which accept a 40mmx40mm axial fan. There are TWO STL files. Please choose and print appropriately. LEFT = with flat surface to the rear, the boxed shape exhaust outlet is BOTTOM LEFT. RIGHT = with flat surface to the rear, the boxed shape exhaust outlet is BOTTOM RIGHT. Print with flat rear on your print bed, I believe the STLs are already in this orientation. My preferred quiet fan is Noctura, this includes rubber fittings which can be cut to length, but if you don't have fittings then you'll need... 4 x m3 nuts 4 x m3x25mm, do not exceed 30mm length (these are to mount a 40x40x20mm deep fan) You'll also need the fittings which you would have normally used to install the 5015 blower fan. You'll use these to secure this adapter using its diagonal screw holes.
