Here's a modified 40MM Fan Duct and Magnetic Mount for part cooling on an Ord Bot Hadron with Bulldog XL extruder and E3DV6 hot end. Of course this is very specific to my setup, but could possibly work with others. Screw the FanDuctMountSliderBase.stl onto the Hadron's x-carriage right side with 3mm screws. Insert magnets into slots making sure to align the polarization so the parts are attracted to each other instead of repelled. Designed for Neodymium Cylindrical 1/4 x 1/4 inches Cylinder/Disc Magnets (search on ebay). There are two sliders, one with a little larger holes named "MoreTolerance". Ended up needing this one when printing in ABS due to shrinkage. Printed fan duct in PETG PRO so didn't need more tolerance on it. Made ducts a little thinner to fit between hot end fan duct and nozzle.
I've also included my modified E3DV6 hot end fan duct, as the stock one was too tall to fit without resting on the heat block of the hot end. Extend out beyond face of Bulldog XL and has slot to fit around mounting bolt. Loosely based on 13DjjC13's version referenced as source, but re-created from scratch.
