OpenBeam Strong Corner Braces

These braces are for assembling lengths of OpenBeam and may also work with other 15mm aluminum extrusions. They can be mixed and combined as needed, and I am adding more as I make them. The walls are 4mm thick all around.

They come in two varieties, with and without bracing. Pieces with braces will be the strongest and best at keeping pieces from wobbling on their installed plane as well as resist twisting forces. Pieces without braces will prevent twisting and use less material to print.
