Ender 3 V3 KE - New upgraded bearing roller for side spool mount filament.

The main difference between my design and the previous ones is that I integrated this bearing onto the original locking mechanism, resizing it to 29.9 mm ( From 30 mm). This makes the locking mechanism 0.01 mm smaller in diameter than the original file available online. Used with SIDE Mount from- https://www.printables.com/model/711231-ender-3-v3-ke-filament-spool-side-mount-toolless

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.
