Bolt Industries PCB ruler

This is my open source custom PCB ruler. Here you'll find everything you need to design your own custom PCB ruler based on the Bolt Industries PCB ruler. If you'd like to get your hands on the original PCB ruler, you can find it on Kickstarter here: https://www.kickstarter.com/projects/1639195067/raspberry-pi-arduino-and-electronics-pcb-ruler-v30
