Review on 🔧 KOOTANS 1Pc 90 Degree Corner Angle Bracket Connection Joint Strip for 10Mm Slot 4545 Aluminum Profile 3D Printer Frame by Junior Samson

These mounts are precision machined and free of burrs or tool marks such as nicks or flared holes. Perfectly smooth. Material - heavy aluminum plate. The finish is satin and I assumed clear iridite passivated or anodized. I used them as is but the surface can be painted if you wish. The price is great, especially considering you get the hardware (with appropriate T-nuts) to install with five bolts in 2020 profiles. My cube printer is extremely stable with these extra parts. Highly recommended.
