After printing out a couple of benchmarks with the upgraded carriage and cooling fan modification I’d noticed that overhangs facing away from the printer were not what I was hoping they would be. I suspected a first candidate for fixing the problem would be to pull the small circuit board out of the fan shroud. I had initially hoped that the board would be tucked away and small enough to not impact print quality; I was wrong. The problem became where to put the board. I was not interested in a complete rewire of the project so I needed a better solution.

Half of an hour in CAD and this is what I came up with. I’d always planned on putting a small fan shroud on each of the cooling fans, why not integrate a small space for the circuit board to tuck it all away? Perhaps I’ll add space for a small button to control the fan without unplugging it.
