As I work on upgrading my RV10 panel I wanted to add a avionics cooling fan. Not wanting to spend $170 for the certified one, I borrowed ideas from other VAF posts and came up with the following.
The picture shows one fan modified and the other with the piece parts ready to be assembled. The fan is available from this site:

I purchased one foot of 5/8 032 wall tubing from ACS to make the cooling ports. I had JB Weld on hand to glue them together. So I have less than $20 for two fans. Thanks to others for your posts on this subject.
