Ruler in Carbide create

We do have a list at: https://wiki.shapeoko.com/index.php/Carbide_Create#Resources

(and apparently merging was already done once)

I’d like to include this sort of thing in my nascent Kickstarter: https://www.kickstarter.com/projects/designinto3d/917478342/preview?ref=pbuild_dashboard#project-preview (link requires one be logged into a Kickstarter account I believe)
