Spool holder

Ball bearing spool holder that fits snuggly onto the frame just like the original holder. With lowered center of gravity and a much shorter pivot, vibrations and oscillations are greatly reduced. Also overall height of the printer is reduced. 4x Ball bearings of 8x16x5mm and four M3 screws are needed to complete. Ball bearing with outer diameter 14-18 should work fine as well. Recommend infill > 30% for strength
