40 mm fan case for Anet A8 extruder

thingiverse

I had an old 12-volt fan from a graphics card kicking around. I chopped up the original fins and designed a whole new set of fins to fit a radial fan and a full case. Then I glued the fan in place with hot glue. It's working like a charm. As per your suggestion, I uploaded a revised design for the new fins with a smaller rim for better airflow. Update 31/10/2017: Following your advice, I turned the fins upside down to boost performance!
