Touch ruler
Raised tactile ruler for the visually impaired and sighted
Rule made by laser cutting, use the SVG file
The principle consists of gluing the three strips with wood glue.
Upper slat (slat with teeth) => cutting and marking
Middle slat (slat with numbers to recover) => while cutting
Lower slat (optional slat) => all cutting
Note: On the SVG file, the numbers on the upper slat are blue, because they only need to be marked, we then use this marking to have the location of the numbers which will also be glued with wood glue.
The large lower slat is optional, but it can be used as a support, for example to install a screw.
