Caliper Radius Gauge – Corner Radius up to 130 mm (prints without support)

This radius gauge allows you to determine the corner radius of parts using a standard caliper.

Tested with a Mahr MarCal and a generic low-cost caliper – compatible with most calipers.

To calculate the corner radius, multiply the caliper reading by 2.4142.

The formula is engraved directly on the tool, together with quick-reference radius values: 5, 10, 15, 20, 25, 30, 40 and 60 mm.

The model is optimized for 0.2 mm layer height, prints without supports, and is designed for clean results on typical FDM printers.

For best readability of the markings, pause the print before layer 41 and change filament color.
