Improved Ender (3, 3 Pro, 5, 5 Plus, 5 Pro) Ball Bearing Filament Spool Holder

thingiverse

Improved Ender Filament Holder with Ball Bearings I had grown tired of the stock filament spool holder on my Ender-5 Pro, so I decided to make some improvements by adding ball bearings and spacers. This modification will work for several printers: Ender 3, 3 Pro, 5, 5 Plus, and 5 Pro. These holders are designed to be tapped lightly onto the existing spool holder (press-fit), making a rubber mallet a useful tool for installation. This creates a tight seal that allows the filament spool to rotate easily while still looking somewhat like the original part. To install these holders, the endcap must be removed by cutting it off (see attached picture). The stock release knob remains functional. The normal endcap requires removal using the stock thumb nut when changing reels, but this compact version eliminates that step if you're tired of dealing with it. I flipped my plate around to make the reverse spool shim unnecessary, so if your configuration is similar to the cut image, use the shim. Ball bearings used: 2x 6906-2RS (30x47x9) DISCLAIMER: This modification requires slight changes to the filament spool holder, which I am not responsible for any damage caused. Only attempt this modification if you know what you're doing.
