radius caliper

Beskrivelse

The idea for this tool comes from sorrenaveria's popular "Radius Caliper (No Computation Required)" that you can find here: https://www.printables.com/model/236582-radius-caliper-no-computation-required The reason for designing a new one is that I wanted it to not have an artificial limit for the minimal radius that can be measured. I also made it to avoid printing long bridge and added holes for M3 screw, for cases where the attachment is not sitting tight enough on the caliper. There are two versions: the small one that I made for my needs can measure radii up to 57 mm, and the larger one that needs build plate at least 220x220 mm to print that can measure radii up to 114 mm. I include STEP and FreeCAD files, so you can modify it to your liking.
