Ender 3 Filament Spool Holder

thingiverse

Universal Ender 3 filament spool holder with 100% 3D printed ball bearing. This design works flawlessly for a variety of filament spool widths and center diameters, with the minimum center diameter being a generous 28.5mm. Important note about the bearing: I created two versions - the 3A is identical to the original "rohingosling" version, while the 3B features axes on every bearing ball. To free the bearing parts, some force may be required, but once they're loose, it functions perfectly. It's crucial to use a silicone lubricant, such as a generic mold release dry silicon spray. UPDATE: I added two new parts - "1 Long" and "5 Long". These modifications should accommodate wider spool filament rolls up to 100mm in width. UPDATE 2: I've recently added two new axes for the newer Ender 3 models that don't employ bolts. The updated files are labeled "1 (new ender)" and "1 (new ender)_Long".
