Kossel effector fan mount

This is a remix of the Folgertech kossel cooler mod. I printed the original, but the vertical fan hits the bed; it's too long for the J-head on my Kossel Mini. So I saved the arm/lever and the fan duct and printed this to attach it against the top of my effector.

Print 2_doublefan and 3_doublefan from the original, plus this part. Mount it between the tower arms on top of the effector base.
