What it does
- Measures both inside & outside curves with the same gauge, dual purpose!
- Complete metric set: 1mm to 50mm in 1mm increments, ready to use

- 5mm hang hole on each gauge keeps your set organized on a pegboard
- Perfect for woodworking, metalworking, and suspension adjustments
Whether you're dialing in a custom build or checking curves on a restoration project, this radius gauge set gives you the precision you need. Each gauge is a 3D printed workshop tool designed to measure both inside and outside radii, no flipping between different tools.
You get two complete sets: metric gauges from 1mm all the way to 50mm (in 1mm steps), plus imperial gauges from 1/16" to 1" (in 1/16" increments). That's serious coverage for whatever radius you're chasing down.
The smart design means the inside edge and outside edge share the same radius, so one gauge does double duty. And each piece has a 5mm hole at the end, making it easy to keep them organized on a hook or ring in your shop.

What it is made of
Designs like this print well in PLA. Compare the materials.
Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
