Universal Filament Spool Holder (for Creality Ender 3, CR10, etc)
This is a Filament Spool Holder designed for Creality printers, including the Ender 3, CR-10, and similar models but may work on other printers as well. It is primarily intended for use in a top-loading position but can also be adapted for side mounting.
The holder requires no bolts or screws for installation, as it fits directly into the frame rails. However, you may need to temporarily remove some bolts to slide the spool holder into place before reinstalling them.
Refer to the attached photos for an example of the installed part. Additionally, the open-source SolidWorks file is included for customization. Feel free to modify and adapt it to suit your needs.
No support is needed. Place the side on the bed.
10% filament is enough.
