We made a useful tool for measuring metal typefaces and spacing material, based on an existing brass tool from the 1950s. The plexi isn’t quite as precise as the metal but good enough for the purpose. The scales (around 20cm long) are shipped in a piece of cardboard, cut using the Snapmark feature.
Each letter of the alphabet can be cut for our keyrings, in black or white plexi.
