### ⭐⭐⭐⭐⭐ Well Made
*by B***N on December 17, 2025*

Well made no burrs. Fit perfectly and made a solid connection between two bars.

### ⭐⭐⭐⭐⭐ Helped square the machine for smoother motion
*by D***I on October 10, 2025*

I bought these for the Ender 5 I own. It's still in pieces at the moment but these corner brackets work exactly as specified. They helped me make the entire printer more square than before my tinkering. The Y axis motion is smoother due to being more square. Absolutely a breeze to use. They sit inside the frame, so they are not unsightly like the original corner brackets. Remember to use thread lock on the grub screws.
