Try Square for 2020 extrusion

A try square designed specifically for 2020 extrusion. I'm using it in the construction of a HyperCube 3d printer.

It includes bolt holes so it can be attached to the extrusion using bolts and slider nuts, this effectively gives you a spare hand while aligning the extrusion.

Each side of the try square is 120mm long by 20mm by 20mm.
