Concave (Inside) Corner Radius Measurement Gauge Set

thingiverse

This is a set of gauges for measuring the radius of inside (concave) corners of real-world objects. I felt it was necessary to be able to insert the tool into a corner to be measured, which is why each gauge is on its own stick. When the whole set is printed, they can be attached together in the center with an M3x20 screw and M3 locknut. Use the "split" option in Slic3r if you only need to print certain ones. SCAD file included for additional customization.
