3D Printed Radius Gauges – Precision Measurement Tool

This project features a set of 3D printed radius gauges designed to help accurately measure the internal and external curvature (radius) of objects. The gauges are neatly organized in a compact holder, making them easy to store, access, and transport.

Each gauge plate contains a precisely modeled curved profile corresponding to a specific radius value. By placing the gauge against an edge or corner, users can quickly determine the correct radius by finding the piece that perfectly matches the curve. The radius value is clearly engraved on each plate, ensuring fast identification during use.

The design focuses on simplicity, functionality, and efficient 3D printing. The thin gauge plates are optimized for FDM printing while maintaining enough rigidity for reliable measurements. The storage base keeps the gauges aligned and prevents them from getting lost, turning the set into a practical desktop tool.

This project demonstrates how 3D printing can produce useful workshop tools quickly and affordably. Instead of purchasing expensive metal gauge sets, makers can print their own customizable versions in different sizes and materials.
