Large Radius Gauge R50–R150, Convex & Concave RADIUS
Print Profile(3)
Description
This radius gauge originated from a real-world need:
In guitar making, I wanted to precisely measure the body of a Strandberg Boden 7 – but I couldn't find a printable radius gauge with larger radii from 50 mm. So, as a CAD designer, I quickly designed one myself.
This elegant, fan-shaped tool was created – precise, functional, and visually appealing.
And the best part: The radius gauge works!
I designed it in 10 mm increments from R50 to R150, ideal for measuring and transferring large curves – whether for guitars, CNC projects, 3D-printed parts, or furniture making.
If there is interest, I can even extend the series to the maximum print bed size, or between radii in 5 mm increments?
Features:
Radii R50-150: R50, R60, R70, R80, R90, R100, R110, R120, R130, R140, R150
Edges: concave & convex per segment
Assembly: 3D-printed axis with 2 knurled nuts
Application: Measuring, marking, checking or transferring curves
Ideal for: Makers, designers, carpenters, guitar builders, bodywork, CNC and 3D printing projects
Space-saving: Foldable like a fan
Printing recommendations:
WARNING! Let the print plate cool down completely, otherwise the gauges will bend when removed.
