About this 3D model

This is my version of the curved fan duct for a Mendelmax 2.0 . It is in one part for simplicity and strength. I had problems with the standard 40mm fan duct which was a 2-piece part. It needed to be screwed together and I found that was a weakness point when I went through several mounting brackets. The parts just fell apart after heavy use at full Mendelmax 2 speeds - which is very fast! UPDATE 17/8/2014: Version 2 part. It is now is a little bit longer (5mm) so the nozzle should be centred now. UPDATE 4/9/2014: Flat version of part that is rotated flat for printing. http://youtu.be/iGj08E992UU UPDATE 4/12/2015: Added Solidworks part file on request of user to modify for their MM2.
