Eryone Thinker S Filament Spool Holder Upgrade

thingiverse

I designed this adapter tube for the original Eryone Thinker S filament holder because the metal rod that the filament rolls spin on was very difficult to turn and caused a lot of resistance. I figured out that by simply sliding this tube over it, the resistance drops significantly and the extruder can push the filament through much more easily. I highly recommend attaching the filament holder not at the top of the Z-axis but rather on the left side of the frame below (as seen in the pictures).
