MK3S+ Fan Addons

Whatever filament should work fine, as there is no real heat issue, but use 0.1mm layers so the curves are smooth.

The 5015 intake will slide and stay on the bolt heads. 

The tail cone will need to be glued(dot of super-glue) onto the back of the fan. I tested it once in a bench setup and the tail cone added 10% to the flow speed.

The updated 4010 conical intake will have to be glued on as well. Not a lot of space to work with here.

UPDATES: 

1.) Did some testing, original intake I had here for the 5015 seems to actually restrict flow by a couple percent in an open, low backpressure anemometer test. Redesigned to a 45° conical, more open shape which shows a couple percent improvement over stock. Installed, the flow will be lower through the duct, so gains might be lower as well.

2.) Redesigned a 45° conical intake for the 4010. Bench test video link, here. Again, seems to be some gains, 10% in the bench test, likely less than that here with the one side cut out for clearance, and increased backpressure from the heatbreak. Also, the Noctua fan might well do better on it's own over the one I bench tested.

If you do any testing, I'd love to hear about it!
