It's an idea.
Not sure how it would look though.

And apparently I did buy a 30mm fan. Think the 25 was on amazon and I ended up getting it from ebay.
Looking at it the 25mm would probably be better.

Second test print underway. Previous clip was 2mm too narrow.

If I reverse the wires on the fan - will it reverse direction ?
or melt ?
I could do with it being the other way round, lol always the way :-)
