So I had a head fan crash tonight. Kinda bad. As the carriage moved to the left and then to 0,0 home, the 40mm Noctura Fan with @jstevewhite slim fan shroud, the entire fan got pulled away, breaking the shroud and pulling a wire out of my hot end thermister.
BUT i found an elegant solution. It's only cost me a small amount of Z-Height. I took the bed off, then removed BOTH of the left Z yokes. I reversed the yokes so the rail car is now below the bed plane, and the vertical part of the yokes are also pointing downward instead of upward. This gives me MUCH more room on the left size so no more fan crashes!

I think this is worth considering. Lose Z height, gain X where the Z extrusions are.
