About this 3D model

EDIT: please see the newer revised edition here that is suitable for the Hexagon hotend. http://www.thingiverse.com/thing:431160 During my 3D printing learning curve I found the requirement for ducted fan to achieve better prints and to successfully bridge. Since the Robo3D there wasn't any suitable fan ducts available on Thingiverse so I decided to try my hand at 3D CAD and design one, needless to say yet another steep learning curve. This is my first design and I wanted to share it as I feel the bracket is a great solid fit for the Robo3D and I want it to help spawn some great fan ducts for the Robo. This duct fits with the E3D v5 nicely. To fit the standard hotend some tweaking is required (I had to file the duct bracket holes downwards a bit and some off the top of the duct brackets so the duct could mount to the X carriage bracket a bit higher, some users have heated the top of the duct and pushed the mounting point downwards). I hope you find this useful and that it assists in producing other/better fan ducts for the Robo3D.
