This is a modification of https://www.youmagine.com/designs/ultimaker-fanduct-v2 and https://www.youmagine.com/designs/umo-fanduct-for-3dsolex-and-e3d-nozzles to use 40mm fans and attempted to create a right side version with the extended mount to get clear of the nozzle. The orginal design are for 50mm fans, as I had a couple of good 40mm fans, I modified the design to mount 40mm fans. Still not printed so I dont know if its a 100% fit. Will print in Colorfabb XT as soon as I get time.
