Magnetic Spool Holder Bracket for Creality CR-10

thingiverse

This is a simple, bearing-based spool holder that attaches directly to the top of the Creality CR-10 control box for smoother filament feeding and adjustable fit for various size spools. Engineered to utilize [625ZZ bearings](https://www.amazon.com/gp/product/B00EDK5GIE/ref=oh_aui_search_detailpage?ie=UTF8&psc=1) and M5x10mm button cap screws, along with washers. Print two of these brackets, inserting a washer between the bearing and printed part to prevent any binding of the bearing. The screw cap on the inside does not require a washer. Designed specifically for three 6mm diameter by 6mm long neodymium magnets that are press-fit into the bracket to securely hold it in place on top of the control box. Adjust the space between each bracket to match the width of your desired spool. I have included a SketchUp source file, allowing you to adjust the diameter of the holes for different size and types of magnets. I find routing filament from underneath the spool directly to the printer works exceptionally well in trapping the filament on the spool and preventing unwinding during retractions for full spools.
