CR-10S Pro Alignment Jig

I noticed that when I attached the upper frame of the printer to the base, the x-axis did not appear to be perpendicular to the y-axis. For some of the items I print, I need the printer to be perfectly square. I designed these brackets to clamp to the y-axis rails and set flush against the x-axis rails in order to square things up. Hopefully these will come in handy for others.
