Robo C2 fan duct mod (new version available)

5/2018 UPDATE: A new and improved version of this has been added here. This new version is much more simple and only takes a few minutes to install. Precision Air Flow

4/2018 UPDATE: V3_REV_B has been added. This closes up the channel from the screw mounting hole, which could potentially direct airflow onto your heatblock. See the picture uploaded, and you will see the difference in V3 to V3_REV_B.

This is a mod for a single extruder on a Robo C2 (also works for a Robo R2) for better airflow to cool your 3d printed parts, directing airflow a little bit better than the stock fan duct, all using the existing fan duct hardware.

A full tutorial on how to install this is here

NOTE: Change your fan settings to turn on at about 10mm height on your print. The better airflow from this shroud can cause thermal runaway errors in the beginning of a print, so turn them down, or off in the beginning of your print settings.
