Made some tweaks based on the comments I saw on the original models as well as a few improvements of my own.

Update: I forgot that the Ender 3 KE has a different spool stand, with an additional part that makes it incompatible with my model. As such, I've updated my model to support the KE stand.Please let me know if it's still incompatible, in order to make my model accurate as I do not own a KE, nor a stand with the filament sensor mount. |
This thing is immovable, the added brackets around the metal part add a ton of rigidity, maybe even too much..
I'm not sure if it always was like this with the original models but this thing is hella sturdy, it doesn't budge at all.
I printed mine with:
- Filament: PLA. I wouldn't recommend PLA, as it can vary in brittleness. Some PLAs will work fine and have a bit of flexibility, but others may be more brittle. I only printed it in PLA cuz it's the only filament I have.
- Layer height: 0.28mm
- Infill pattern: Gyroid
- Infill density: 15%
- Supports: Organic
- Perimeters: 4 (probably excessive. 3 should be okay too)
In order to ensure better longevity, you can add a model modifier in your slicer to increase the infill in around the middle of the model. 50% is very rigid.
Printed this for my Ender 3 V3 SE, though it should work on the KE as I think they have the same base and gantry design.
Installation
Prepare two M5 nyloc nuts into the provided holes
Take off the plastic holder on the printer's spool holder and slide it from the bottom up
(i don't know how to do animations in freecad)
Screw in the M5 screws provided with the printer for securing the spool holder
Reattach the plastic spool holder onto the metal part
Snap the whole thing, starting from the bottom, and up onto the gantry with the force of a thousand Thanoses, reattach the plastic holder and you're done.
If you find that the front clip doesn't want to attach to the front of your gantry, you can use slip joint pliers padded with a folded piece of paper towel to prevent scratches. Depending on the flexibility of your filament, it may either snap or bend around nicely. Even if it snaps like it did in my case, it doesn't affect the rigidity of the clip, as it still offers plenty of support.
(I had to recreate the whole thing cuz STLs suuuuuuck, and as such, please enjoy the STEP file I've attached, happy remixing)
