End-Stop ring, to keep the spool on the adapter. (Pic 3, is what happened without it)
Print the adapter upright, with NO SUPPORTS. (also, the ring, of course).
I printed in PLA on a CR10-SE, and PET-G on a P1S. Both work fine.
I used 3 walls, 15% infill.
The author remixed this model.
The original model is excellent. It will fit your Enders, CR-10s, Clones, and more. However, my spools were drifting, on my CR10-SE, and comming off the adapter, at the arm end. They would end up diagonal, and dragging as they turn. If this happens to you, add this stopper.
Ender, the END STOP. Print this ring, slide it on 1st, then slide on the adapter. Both will JUST fit, and it will turn freely. Be sure the adapter snaps on.
