This is a Sonic Pad mount remix from auroratechchannel. This remix allows you to use the Creality Ender 5 S1 enclosure with the sonic pad attached. Whereas the previous version was too short and the door of the enclosure would catch on the bottom of the Sonic Pad. I also increased it's Y axis to allow the hot end to clear the cables from the back of the sonic pad better.
The author remixed this model.
