Stronger Creality CR6 CR-6 SE Part Cooling Fan Duct Adapter for quiet 40mm fan with PTFE and cable Support

thingiverse

I basically made the fan duct stronger in a few weak areas, made it easier to print, moved it down and changed the angle a bit (to get my 4020 fan to fit under the bed levelling sensor wires). I made the mounting bracket massively stronger and combined it with my thing here so that it offers support for the PTFE tube for accurate bed levelling and routes the cables via the x-axis stepper so there is no strain on the cable or the PTFE tube https://www.thingiverse.com/thing:4657122 There is also a non-angled version of the fan duct if you're just using a 4010 fan that's a bit stronger and easier to print than the original. The original design is amazing, but really thin and weak. This is much thicker and really strongly mounted with two bolts, two parts that clip around the rollers and it rests on top of the metal plate. I printed in PETG for better strength and temperature resistance. I cannot be bothered to resize all my images to under 500kb, so see my make for loads of phhotos showing how it's mounted and the differences in the angle from stock. Supports are not needed for the fan duct, but they definitely are for the top mounting bracket. I've got Sunon Maglev fans running at 20v instead of 24v using a 220ohm resistor and they are really quiet and still offer better cooling than stock.

It is 3.2mm at the narrowest part. I've got no interest in printing this version, so if anyone does, please let me know if it works!
