About this 3D model

This is a low profile fan duct for use with the Rostock style 3-D printers and a standard 40mm fan. I designed it for my Rostock MAX with the J-Head Groove Mount from Trick Laser with the Aluhotend. It should work with the stock SeeMeCnc hotend as well, and would probably work with a similarly mounted E3D hotend. http://www.youtube.com/watch?v=GZc7n4DtgF4
