This is a Remix of the original model over at Thingiverse: https://www.thingiverse.com/thing:5488467 for those of you who'd like to keep their router cool, or just have a spare fan lying around… :)

Just made it as a solid base variant, which can be printed without bridges - and thus - without supports.

Obviosuly, it shouldn't be used on a flat surface without room for the fan to breathe. Add some feet to the base if you've got no alternative.

Keeps my Fritzbox around the 50-60°C range (with 20-22°C ambient), instead of the usual 80-90°C without the fan.
