Fan adaptor: 40mm to 60mm

Quickly made adaptor.
Printed with Cura 3.1 option "Make Overhang printable" - 60° rather than adding chamfers etc in the design.
So if you want to avoid support, you know what to do.
This 60mm 12V 0.1A fans I found in my scrap box, must be 15-20years old and replace my 40mm 12V 0.09A fan.
Just a try out. Bigger is better??


I've put this one on top of my cooler https://www.thingiverse.com/thing:2684486.
