9g Keychain Radius Gauge Set 1-30mm Dia. In & Out

Boost MeTo support my work and help bring practical, beginner-friendly designs like this to more makers. Your support drives innovation and keeps the 3D printing community thriving!

 

Important Note:   The numbers on this tool represent the diameter, not the radius. If you need to measure the radius, simply divide the indicated number by two. This ensures the tool remains versatile for a variety of applications.   For those who prefer the radius values displayed directly on the tool, you can scale the design to 200%. At this size, the squares will measure 60mm, making them less suitable for a keychain but ideal for a larger, desktop-friendly version.

 

This compact and practical Radius Gauge Set is perfect for quick and precise measurements, covering inner and outer radii from 1mm to 30mm. Designed to fit conveniently on a keychain, it uses just 9g of filament, making it a lightweight and efficient tool for any maker.

 

The included 3mf file features two plates: one with a single-color design and another with numbers in a separate filament color, ideal for printers capable of multi-color printing. Perfect for customization, portability, and accuracy!
