Steel Ruler Vernier

thingiverse

Wanting to measure with precision? Look no further! This single STL file transforms your 26mm steel ruler into a precise measuring tool that's perfect for simple measurement jobs. The clever design of these jaws makes them especially useful when measuring round objects. Note: Because of the way the jaws are designed, you'll need to account for the first few millimeters of the ruler being used to secure the jaws in place, so your measurements will have an offset.
