PDF

Designed around Dometic RV fridge cooling fins and an Arctic F8 80mm 12v fan. The fan is supposed to improve cooling efficiency of the unit by circulating air across the fins. I attached mine on the opposite side from the internal light so I've included a rudimentary wire clip for cable management. There are 2 files for mounting a buck converter ( https://www.amazon.com/gp/product/B01GJ0SC2C ) if the full 12v is too noisy.

I've seen a few "production" offerings for this type of thing on amazon and eBay, but the asking prices were steep. There should easily be room for 3 of these if needed.

Update 19/08/08: Added a couple of pics. 1 of the cooling fin design. 2 of the previous version w/ the fan. I haven't printed the posted STL w/ the wire notch (that was the only change). I just cut a hole in the one I had. I'll upload images of it installed once I get it wired into the light circuit. The test print fit snug in the cooling fins and the fan has a small clearance from the mount and the fins.
