It was a pain to constantly be taking the toolhead cover off the V3 Plus to change nozzles, so I designed this to solve that problem. One change made from the base toolhead is that the fan now mounts to the toolhead and not the cover, making it so that the fan does not have to be unplugged to make nozzle changes. It is a little bit wider and potrudes further out from the stock toolhead, but it does not affect print area. While I have not had any issues (beyond the one mentioned below and have noted a fix), the toolhead cover could detach while printing, use at you own risk.  That being said I have printed on the stock Orca speeds which get up to 500mm/s and have had no issues. 

It reuses the original fan duct from the toolhead which can be carefully popped out by pushing on the right side and prying it up. Other hardware needed is:

  • 8 - 6*3 Magnets
  • 2 - M3 * 25mm screws (the originals are M3  * 30 and would poke through and maybe short the toolhead board behind
  • 2 - M3 * 3 * 4.2 Brass heat set inserts (though you maybe able to just screw into the plastic)
  • Glue for magnets
     

I printed this in ASA with 40% infill, 4 walls. I would recommend ASA or ABS as it will be near the nozzle, but you might be able to get away with PETG. I printed with auto tree supports with the cowl printed upright and the bracket with the fan mount against the build plate. See the 3MF files. I also am including the step file incase anyone wants to remix either for the V3 (not plus) or for any other reason.  

UPDATE 1/20/25 - PLEASE GLUE YOUR MAGNETS IN! The press-fit magnets in mine eventually got loose enough when it was warm enough that they came out and as a result, the print head cover came loose and was tossed from the printer, resulting in a print failure. Nothing catastrophic, but not preferable.
