Filament Spool Holder for the Ender 3 ** This spool holder is designed to always keep your filament firm. Simply adjust it to fit. It's pictured here being used on my enclosure from [enclosurelab.com](https://enclosurelab.com/), but it will work just fine in your normal metal holder that came with your Creality Ender 3 printer. **Parts Needed** ● 1x M8x120mm Hex headed bolt ([I used this one from Bunnings](https://www.bunnings.com.au/zenith-m8-x-120mm-hot-dipped-galvanised-hex-head-bolt-and-nut_p2448937)) ● 3x Standard 608ZZ ball-bearings (8x22x7mm) ● 1x M8 Hex nut **Print Settings** Material: PLA Infill: 40%
