Summary

This is just a "clean" corner that you can use to remix. Use it to make your own corner mounted...

The corner on the Ender 3 S1 differs from the Ender 3 S1 Pro model and has a very different design over the pro model. If you mirror it you should get a right corner. The tear shaped holes indicate which way is up.

There are two variations. A larger one covering the whole corner and a smaller one. Use whichever one you prefer.

Use M5x20 bolts to mount.

Note: The angles are not 100% correct, but it perfectly workable and you won't notice it.
