Gravity Auto Rewinding Spool Holder for Prusa i3 Frame

I've always thought the Gravity Spoolholder by @MichalFanta was a great idea, but I was content with my regular spool holder. Then I saw @Steven_36896 's design and I thought it would be great to put that on the frame of my MK3S+ to save space. I mirrored the Right side to get the Left side.
