Radius Gauge — 100% 3D-Printed Part
This is a fully 3D-printed radius measurement tool. It's designed for makers who want a quick, precise, and compact way to measure corner radius or round object radius. All components print without supports, require no screws, and snap together easily for a fast and frustration-free assembly. The measurement can be read directly, no multiplication needed.
Updates:
- 2 Dec 2025 - The shape of the marker (indicator) is updated so it has more face contact to the plate thus easier to print
- 26 Nov 2025 - Prime tower added to the 4th plate for the multi-color print profile
Note:
- For imperial scale, I have added the raw model file for the Top Case. So you can download and print that separately. I didn't print it out so I don't have a real picture to make a new print profile. If you print the imperial one, please share some pictures for others to see. Thank you.
Key Features
- 100% printed parts – No hardware required. Every part of the tool is fully 3D-printed.
- Easy assembly – Snap-fit design makes it super easy to assemble without any screws.
- Support-free design – All parts print cleanly on any FDM printer.
- Compact and ergonomic – Comfortable to hold, lightweight, and small enough to keep on your desk or tool wall.
- Smooth sliding indicator – A calibrated scale with a colored slider makes readings clear and precise.
- Accurate radius measurement – Measures radii from 0–50 mm.
- Functional thumb buttons – Bottom slider button gives easy-to-control measurement.
How It Works
- Insert the curved object between the two jaws.
- Slide the button until the middle bar touch the curvature.
- Read the radius directly from the printed scale.
