FLSUN QQ-S Filament Spool Holder

thingiverse

This ball bearing supported spool holder for my FLSUN QQ-S Pro feeds much smoother and avoids the tower shakes from time to time. Although very similar and inspired by https://www.thingiverse.com/thing:4261119, I fully redesigned it so it would fit some of my smaller spools. On top, I wanted to reuse the metal stand of the original spool holder of the printer. The cylinder is not a standard Thinkercad one since those have only up to 64 segments but I found a 'perfect' smooth one somewhere on the web. You require 2 bearings of type "608zz Metal Double Shielded Miniature Deep Groove Ball Bearings (8 mm x 22 mm x 7 mm)" which are widely available. I paid 8 euros for 20 pieces. I printed all the pieces vertical with support for the 2 bigger parts.
