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.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
