Gridfinity Cable Spool Holder – Hand-Tightening Knob Remix

This is a remix of the Gridfinity Cable Spool Holder. I designed a hand-tightening knob that fits perfectly in the center shaft, allowing you to tighten or loosen the spool quickly without any tools . The knob is designed so that: No support is required during printing It can be printed on its side , giving it much higher strength and durability It maintains full compatibility with the original model Just print, insert, and enjoy easier spool management! If you try it, let me know how it works for you 😊
