RadGauge-Dual MEGA (radius up to 80mm)

🌀 RadGauge – Radius Measurement Tool

Radgauge is an innovative device designed to quickly and accurately measure the radius of a curved surface. Currently, various designs are available depending on the measurement range and function, and the characteristics of each design can be checked in the table below.

RadGauge-Dual Mega

 

When I unveiled the RadGauge-Dual model a few days ago, I expected it to be less popular than the original RadGauge, but the response exceeded my expectations.

Of course, this was partly due to the addition of an internal radius measurement feature, which the original RadGauge lacked. But perhaps more importantly, many people felt the same sense of engineering pleasure I felt from the device's movement.

So, I designed the MEGA model, which uses the same mechanism to measure radii up to 80mm.

 

This model also adds an internal radius measurement feature and is similar in size to the original MAGA version, but thinner. While the rotating pointer structure limits its ability to be thinner due to durability considerations, the sliding scale and pointer allow for a thinner design due to their structural advantages.

 

This model measures the inner radius to a minimum of 5 mm. For smaller radii, use the NANO model.

Originally it's designed for metric units users but there is a profile including inch scale separately.

 

The method of use is the same as for all existing RadGauge models.

 

!!CAUSION!!

Please note that if the build plate has poor adhesion, the scale may not print properly.

For smooth sliding, the use of a smooth plate is recommended.

Added inch scale profile. This profile only contains scale models, so you can use them instead of mm scales.
