2-Axis metric ruler

A set of rulers with right-angles built in. I was copying a fairly large complex object into modeling software and found myself needing to measure offset dimensions. I didn't have a great way to do it so I invented this. Two metric rulers, one with a right angle built in, held together with a sliding block that also maintains a right angle. This allows you to measure in 2 axes at once. My use case was to position the base against the object, then slide the rulers until the tip contacted the spot I wanted to measure. That would then tell me that the spot is ZZ millimeters above the reference plane and XX millimeters laterally displaced from it. The photo probably explains the usage better than words.

The "joiner" block printed fine without supports on my Bambu A1. In order to keep the right angle, the tolerances have to be pretty tight and I think support interface layers would really mess with that.

Important, make sure your slicer imports this as EXACTLY 250mm x 120mm x 35mm
