The main difference between my design and the previous ones is that I integrated this bearing onto the original locking mechanism ( From -https://www.printables.com/en/model/710011-ender-3-v3-ke-se-spool-roller-easy-to-print) , resizing it to 29.9 mm FROM 30MM. This makes the locking mechanism 0.01 mm smaller in diameter than the original file available HERE online.

Also* to uploader of side mount above , TY
The author remixed this model.
I took the idea from a couple of designs I found online and combined them to create a roller for the side mount. This allows for easier spool release and reduces stress on the teeth of the hot end, ultimately increasing its lifespan.
