40MM Fan Duct for Solidoodle Hotend
You'll have to excuse this hacked together version of the one I made for myself. I wanted to get something out there that was universal for 40MM x anything Fans. I borrowed the fan mount idea from Ichibey http://www.thingiverse.com/thing:110947 and the fan duct was designed after Ian's for the original Jigsaw with a couple changes. The hotend hole is enlarged to keep the sides from melting (that seemed to be a common problem for me and a couple others). I made mine a lot lower profile.
One issue that I still have is that this doesn't just cool the filament coming out of the nozzle. It creates a large pocket of air which works extremely well for me, but it might not be ideal for others. I am not planning on posting this to thingiverse since I am not 100 percent happy with it. If anyone wants to mess around with the original files let me know. For now, this should get you moving until another mount comes out that you like.
The pictured fan is my prototype for my printrbot hotend. It is ugly and was printed at 180mm/s so don't judge but this is pretty much what it looks like.
