This is a fan mount designed for the underside of the x-carriage on the printrbot GO with maximum flexibility in mind.
This is highly customizable using the customizer for different heights, ball joint sizes, fan sizes, screw and nut sizes, etc. Knock yourself out.
This probably prints better with a fan. Hahahahahahaha. No, seriously, it does.
The uploaded STL of all three pieces has a duct for a 35 mm fan. I haven't decided yet what the largest fan I can fit into the tight confines of the GO, so I'll leave this as a work in progress until I get mine dialled in. I included an STL of the duct for a 40mm fan as well.
Be sure to include an @pause command to insert the trapped nut. The vertical holes for screws all employ nophead's polyholes module for improved fit when FDM 3d printed.
Also added a vertical height correction for the trapped nut as I was having a hard time getting it to line up with the screw hole precisely.
9-1-13 Added separate parameter for duct wall thickness (was formerly the same as clip thickness) so I could make a thinner, lighter duct.
