When I was a kid, I used to have this odd little design ruler. I have no idea where I got it, but it had straight lines, curves, shapes and such all built into it. I have seen similar things online, but since I have a machine that makes cool stuff, why not make it myself.
This is mostly from memory and may be of use to no one but me. However, as a kid, I designed mazes, space ships and all manner of oddities with it. The shapes are all sized as 1 inch, 3/4 inch, 1/2 inch, 1/4 inch, 1/8 inch. The degrees are the ones I use the most. The left edge is 90 degrees and the triangle coming down from that is 45 degrees.
I am sure some kind soul will come along shortly and tell me the name of this kind of ruler (and likely point out my deviations, because it’s the internet)
Feel free to add to it, modify it and make it.
