This is modification of "Ender 3 V3 SE Side Mount Spool Holder and Filament Guide
by Jakesurprenant"

Moves the filament spool from the top of the printer's gantry to the side, behind the screen. This modification improves print quality (reducing ghosting) at higher speeds by minimizing gantry wobble caused by the spool's weight on the Z-axis. The three additional parts guide the filament from the spool to the extruder. The entire setup can be printed in one go, reducing height limitations. All four parts are arranged for 3D printing with support.

Changes:

For the side-mounted filament holder, I've moved both screws 4mm to the back, ensuring that the spool doesn't collide with the display when using the default filament spool holder. In the original version, my filament spool would often collide with the screen during printing.

For the filament_guide_base, I've made significant changes. It's now easier to attach to the gantry and includes two locks for secure placement. The original version only had one lock, which caused the base to slide down along the Z-axis over time.

Additionally, I've designed a new spool and spool locker, eliminating the old filament guide wheel and wheel cover that used to break down during printing.
