Duplicator 4, Blower duct

thingiverse

I designed this blower duct as I preferred to see what was happening on my 3D printer. I was using a Active Cooling Fan Duct for Replicator 1 / Duplicator 4 / FlashForge (available at http://www.thingiverse.com/thing:295317) and it worked fantastically well, but it blocked the view from the front of my printer. This blower moves much more air than the previous 40x40x10 fan I used so it cools better, great for larger overhangs. The only downside is that it is a bit noisier too. **Instructions:** I was able to print this duct without supports (although some other form of cooling may be required). A 50x50x20 radial fan purchased from nz.rs-online.com/web/p/blowers/0126414 is used, and since it's a 12V fan I had to use a separate power supply until I can get a 24V version. The mounting clips are not perfect but they work. The major part still needs some tweaking but they do hold the blower in place firmly.
