Neotoy Speed Square (metric)

Inspired by my Swanson speed square, I wanted something a little faster and more portable. The internal back-facing floating print-in-place hinge allows you to level the square on either side in seconds. The rails on each edge make it possible to move or remove the backstop. Measurement marks every CM, on both the backstop and the rails. Structure is optimized for strength and lightness while having that old-world crafted tool charm.
