Geeetech filament spool holder arm 20mm square grab

thingiverse

Here's what I came up with: I need a filament spool holder, so I created one. You can attach M3 screws that are longer than the originals to prevent any left or right movement and add a washer for extra stability. The V3 version features reinforced corners and critical points for added strength. My printer is a Geeetech A10M, but this design would work with any 20mm square-sectioned upper arm. I used M8 screws and other hardware for the spool, which adds to its durability. This filament holder pairs perfectly with the thing from Thingiverse: https://www.thingiverse.com/thing:2433875 To make it even more robust, I used a 50% infill. While stronger materials like ABS or PETG would be ideal, PLA works just fine for this project.
