Corner L shape to 20mm profil

thingiverse

The corner fitting for a 20mm aluminum extrusion system is typically an L-shaped piece designed specifically to attach at the corner of two profiles. It securely holds them together, allowing users to construct large, stable frames while also creating precise 90-degree angles throughout their project. These connectors can be removed later on, making it easier to modify or reconfigure a framework without permanently altering its layout.
