CR10 Spool shaft bushing update

thingiverse

Purchased my CR-10 printer 3 weeks ago and this update enables the spool holder bushing to work seamlessly with your stock spool holder tube. The modified design shortens the tube length to 80 mm, expands the inside diameter to 32 mm, and trims the nut length to 24 mm for a precise thread pitch. To ensure compatibility, grab a digital caliper and measure your spool tube length from the metal support arm to the shoulder of the plastic retaining nut when it's screwed all the way onto the spool holder tube. It should be slightly longer than the 80 mm bushing. Additionally, measure the diameter of the spool holder tube to confirm it's slightly smaller than the 32 mm inside diameter of the bushing. After installation, roll the bushing on the original tube with the original retaining nut hand-tightened; it should spin freely and smoothly.
