Fan add-on for this excellent carriage design. Utilises cheap and commonly available PCB fans - I found these on Fleabay for 95 cents each. I have been running with one of these fans without a shroud on my existing Mendel Prusa and will use one each end on the new printer I am building.
The holder does have screw pilot holes printed but I find my fan just presses in without the need for screws or glue.

28 September - added a shorter arm version that fits better on the x-carriages I have designed recently.


Print it and hang it off your x-carriage.
I'm using two of these, one each end.
3 perimeters, 3 layers, 0.35 nozzle, 0.25mm layer height, 25% infill at 90 degrees fill angle.

On my MendelMax, there is only 41mm between the two smooth rods in the X-drive. I sanded 1.5 mm of each of the two upper corners.

I went away from this design for that reason and also because the side mounted fans can limit the x-axis travel on narrower machines. I now think the fan or fans should be mounted fore and aft where they can't get in the way on anything and I have designed several carriages with this in mind.
