Hole Size Test Gauge (2 mm – 10.9 mm, 0.1mm Steps)

This precision hole size calibration tool is designed for testing the dimensional accuracy of your 3D printer when printing small circular holes. The gauge includes holes ranging from 2.0 mm to 10.9 mm, increasing in 0.1 mm increments (a total of 90 holes), allowing for fine calibration of tolerances, especially important in engineering, mechanical, and functional prints.
