Folding X-Wing Range Ruler

A folding ruler for X-Wing still in prototype. I have another version I will be testing as well. This one should be a print in place if I made it properly.

I printed this out and it works ok, but I think it needs a few more iterations. It is too loose for my liking and doesn't work as a multi-ruler for R1, R2, & R3 as easily as I was hoping.
