I was trying to design a toolhead a tad bigger on the right to stop having to jam my wires and damaging them from the lack of room in it... then, after a week of searching and trying, found this one from Gideon Tonkinson @TonkyTinkers_23644400 at https://www.printaxxxx.com/model/1153936-magnetic-toolhead-cover-ender-3-v3-plus/files

==========

===> V2_"VERSIONS" ===> I used OnShape to add the Creality Logo and Name to the Original Model from Gideon.

--> I adapted it and created a depression in middle where I printed and used CA glue for a think layer and the Creality Logo on it to show with the Light through

--- V2_ version is printed with a "depression" in the cowl (the one I did) and printed the "Logo Plate" separately and used CA glue to glue it one (used scissor to trim it a tad more)

--- V3_ version uses a CSF if you want to print it with the Logo already on it

I used a White PETG and the Green Creality logo in Sunlu Green PETG. I added a "pause" in the Creality slicer so I could change my filament color to the green and re-sliced it before I started my print. I still had a little bit of trimming for the thin layer to sit as nicely as it could... LOVE the results! Looks SLICK and AWESOME !!! ; ) 3 walls, 0.16 as recommended and 0.4 mm wide. manual thin tree supports. infill at 25% Cubic.

---> Print with Supports and the COVER/ cowl ON IT’S SIDE for a nicer print finish!!!

My 6mm x 3mm thick magnets were a tad thick, so I used my soldering iron to heat them sligthly and soften the PETG around it to sink them in and have them bond better with the PETG! ; )

-- Details from Gideon

-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 prefe
