• Radius measurement was incorrect due to incorrect application of the ‘decorative’ edge. Resulting in a 0.7mm radius measurement error. This has now been corrected.
• Increased the size of text slightly on the joining ledge to enhance visibility.

About

A compact (expanded) "coaster-sized” measurement gauge to determine the inner radius/diameter of a circle/corner/curve in millimetres, ranging from 22-40mm.

Built to be fully compatible/connectable with the original fillet gauges from AMT. As well as providing a larger radius size, the larger version also sports an improved connection method using ‘crush ribs’, more commonly used in injecting moulding to create perfect press-fit parts (this also reduces the likelihood of parts not fitting due to tolerance differences.

For easier connecting, this model also indicates the joining ridge on how to fit the “embracing gauge” inside it.

Stylistically, this part is based on the original “central gauge version 3” and “embracing gauge version 2” design.

Printing

Follow the instructions for the original design when printing this piece.

For those with a printer with automatic colour changing and a slicer with “filament painting” available, it's very straightforward to paint the different filament colours for the recessed numbers/edges using a fill tool.
