PCB Ruler

$6.90 USD $0.00 USD

A keyboard-themed PCB ruler with useful features. This ruler was created to solve some obvious problems with most flat rulers. It's designed with both a right and left-handed scale, meaning it can be used to measure in any orientation, while always having numbering that's right side up.

The scales are aligned to the edge of the ruler, making it easy to start measuring from hard-to-reach places. The graduation lengths are tuned to be as readable as possible, all while maintaining a well-proportioned visual feel consisting of keyboard related footprints sprinkled throughout.

Other Info:

  • This is a cool looking ruler, it is not a working pcb
  • Some component footprints/silkscreens were slightly modified for visual appeal, they should not be used as design reference tools
  • Similar rigidity to a 0.8mm thick steel ruler
  • Unfortunately radius "gauge" was misspelled on the back side, this will be fixed in future versions
  • Acceptable quality standards document here
  • Thanks to keebio & ai03 for sharing some of the footprints used in this ruler
