40mm centrifugal hotend fan converter for Prusa I3 Mk2 and clones

This is a prototype for my second Prusa I3 Mk2 clone(-ish) build: I have not used it yet. I wanted to use a 40mm x 40mm x 20mm centrifugal fan instead of the standard 30mm x 30mm fan used to cool the E3D V6 style hotend the Prusa I3 Mk2 extruder body is designed for. I am expecting this to be quieter and prove less problematic for the modified X endstop mount (see Tom Sanladerer's "Dolly" at https://toms3d.org/2017/02/23/building-cheapest-possible-prusa-i3-mk2/) Printed out of PLA without supports and with 40% infill.
