This is a quick little box to hide your Ender 3 S1 controller ribbon after you convert to the Sonic Pad. I designed this to make switching between the Sonic Pad and the default controller quick and easy. It keeps the ribbon hidden without having to tape it to the bottom of the printer or removing the bottom cover and tucking it away inside.

Just roll the ribbon up without twisting it, put it in the box and mount the box to the side of the printer using the factory screws.

I elected to print it with the screw hole side down, but either way you'll want to use supports.
