Corner Brace for 20mm Aluminum Extrusion

Neat little corner brace for joining 20x20mm aluminum extrusion. Bolt holes are M5 diameter so you could use M4 bolts as well. Slightly beveled bolt head insets for easier printing.

I like to print things like this with 50% or higher infill. It's a small piece so reduce your heat and speed. Printing multiple helps to allow part to cool while printing although you may encounter stringing!
