Description

Replaces the original material cooling fan, which has significant amount of back-blast (, i.e. inefficient,) with an impeller type fan, and a fan duct and nozzle design similar to that on a Replicator 2.
Print quality is improved, but nozzle design still needs improvements. I bought my fan at an electronic parts supply store. It 

Part was printed in PLA  on my Ultimaker using Cura 14.03.
Designed using ViaCAD v9.

1. Print part at 0.2mm layer, 80%~100% fill, no support.
2. Tear out support structures.
3. Replace connector on fan if necessary. 
4. Mount fan to printed part using 20mm long screws and nuts.
5. Mounts directly to carriage thumb screws using 2 nuts.
6. Connect and tidy up wiring.
