Cooling fan test

This is a quick little test for cooling fans. This can be run in about 10-15 minutes. This was put together so that I could compare the normal fan duct of a Wanhao i3 Plus with my Streamliner design. I think you can guess which is which in the example. :D https://www.thingiverse.com/thing:2442234 Category: 3D Printing Tests
