Flat Radius Gauge

Original Radius Gauge Ruler: Used for measuring radiuses, 150mm long and 25mm wide. Radius sizes are 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 8, 9, 10, 11, 12, covering most daily needs. For more accurate radiuses, enable the precise outer wall function in the slicing software (version 2.10), with the wall order set to outer-then-inner. I create this remix to use negative numbers if you don't have a Multi-color printer
