Slide-In Dual Fan Mount for Zortrax M200

UPDATE NOV 2017:

I've stopped development of this, because this fan mount

eliminates the crossbar behind the hot end, which makes removal of the fans unnecessary when changing the hot end. It's a better way.

NOTE: This is a work-in-progress, and there are some known issues. Some M200s only have three mounting holes in the heatsink. The slide mount is too tight. Some walls are very thin and fragile. I will continue refining the design as time permits.

ccc's wonderful dual fan mount has become a classic and is a must-do mod for the M200, improving part cooling tremendously, not to mention making your printer look extra-badass as well. The support bar for the left fan, however, tends to be in the way when doing extruder maintenance, and removing the fan(s) on the M200 is a real pain, involving awkward angles with hex drivers under the heatsink, and a loose spacer part.

This Thing features two "rails" mounted more less permanently to the heatsink, and a duct part to which both fans are mounted. The duct simply slides to the rear of the printer along with both fans whenever extruder maintenance needs to be done.

One thing to be aware of is that you must have enough slack in the right fan wiring to move it back and forth freely.

I heartily recommend Noctua fans for this application - they're quiet, reliable, blow just the right amount of air, and they have recesses for the mounting bolt heads.
