About this 3D model

It was an idea from "Hardwarekiller". He asked me to design a fan duct for a 50x50 cooling fan and with the possibility to mount an angel eye on it. To get an idea how about this could look like we found this fan duct: http://www.thingiverse.com/thing:17035 I never had experience on printed parts before. So I had to learn a lot till I found a design that meets his wishes and is printable as well. And this is what came out and of course it is printable without support. We have printed it for several printers and they all work fine. The angel eye can be bonded easily underneath the three foots. The height is 30.7 mm. If you need another size feel free to ask for it. I then will create one more version. For my Printrbot I designed a higher version with flattened circular duct to avoid collision to the x-carriage. But it requires to use my own designed x-carriage and extruder mount: http://www.thingiverse.com/thing:37009
