Simpler metric screw measuring device M2-M12 (Blank back side) - 70mm

Just a simpler version of metric system screw from my other model here M2 / 2.5 / 3 / 4 / 5 / 6 / 7 / 8 / 9 / 10 / 11 / 12 on the front with screws and just a simple clean and blank side on the back

As usual, it could measure screws length from 4 to 70 mm.
