Description
They aren't available anymore. I have two of the original rulers. So I made a homage to this formerly very useful office tool that we used to call the WGR.
You can print in any color you want or even multicolor, but the original was just a mild green almost an olive.
The original was just under 14 inches long and had a 150MM scale on the left side and a 6 inch scale on the right. Since I'm making this model Prusa friendly I have made it 100M on the left and 5 inches on the right. Total length is 10 inches long. So the 5in point is also your half way point.
The top ridges allow you to draw a wiggly line to add attention to your content.
Print with standard settings. Maybe consider a bump to 20% infill for strength but 15% will do. Align diagonally on the plate so that it fits on a Prusa standard plate.
