Creality CR10 Spool holder

thingiverse

The standard spool holder has been driving me crazy for a while. This one boasts a much smoother operation and doesn't cause any drag on the filament for the extruder mechanism at all. It's almost completely frictionless. There is absolutely no resistance to the extruder feed mechanism and the spool doesn't get that annoying pendulum rock happening when you print something that does a lot of retractions. I designed it to fit seamlessly on the CR10 control box, replacing the standard spool holder entirely. The bracket(s) can be easily moved to accommodate any width of spool roll with absolute precision. I added rubber pieces to grip the box securely by cutting and gluing them in place. I also glued rubber to the ends of the bolts, which aids with grip significantly. The bolt has a very fine thread, so it won't print well if you slice it with layer heights larger than .1. I printed it at .2, but then used an M12 tap and die to clean up the threads perfectly. Print the brackets that the bearings fit into at 100% infill for maximum strength. Otherwise, the lobes will not be strong enough to push the bearings on securely. You'll need to purchase four 608 bearings. They only cost a couple of dollars each from a local bearing shop (they're a very common size). Once the bearings are fitted to the brackets, the bearing assemblies fit snugly into the clamp brackets without any glue required at all.
