b2x X-Carriage Bed Fan Mount Mod

The original holder and the donut screw hole doesn't align well for my print, so I extend the attachment part of the holder by 2mm and decrease the length of the hood by 2mm to give a better fit. The donut can be downloaded from the original thing.

I've also increase the size of the nut trap by a little bit.
