Customizable spool holder axle for Creality printers (With or without bearings)

thingiverse

Most Creality printers come equipped with a metal spool mount. A plastic rod is inserted into the mount, and secured in place by two plastic nuts. The mount functions well, except when larger spools of filament like 2.3kg or 3kg spools need to be mounted. This customizable design serves as an assembly for a longer rod to accommodate bigger spools. I installed it on top of my printer using M3 nuts and M3 bolts, including [this design](https://www.thingiverse.com/thing:3050607) to mount it onto the 20mm aluminium profile. You can customize the design to utilize bearings (standard settings fit 608 bearings), allowing the spool to turn very smoothly. Customizing the design to use other bearing measurements should also be straightforward. Another option is to print the axle without any bearings. In this case, the entire assembly consists of a single part. Most measurements are customizable to suit your own needs. (See SCAD file.) I printed it using PETG, since the part requires sufficient strength to hold heavy spools. (With 0.2mm layer height and a 0.8mm nozzle.) **Notes:** * You will need the plastic nuts delivered with the printer in order to install the printed axle. * When printing the assembly with bearings, you'll have to drive the bearing support rod through the main axle. I achieved this by simply hammering the two parts together against a solid surface with my hands. * This design is created using [OpenSCAD](https://www.openscad.org/). You will need to install it in order to customize the design.
