Slide-on stepper cooling shrouds

[madoverlord 0]

I've been doing some design exercises to teach myself Viacad, and one of the things I've come up with is a cooling shroud for the X, Y and Extruder steppers. One size fits all, it just slides on with an optional tension lock-bolt. It accepts 40mm fans -- I am running 1 24v and 2 12v fans in series-parallel off the 19v LED output.

With some tiny quiet fans sucking air out of the shrouds, my steppers have gone from almost too hot to touch to body-temperature or a little higher.

Hope it helps, and if you have suggestions for improvements, let me know.
