If you want to support me you can now nominate me and my designs for the Printables Awards 2025! :)

The tool has two inner faces set at 90°, which are pressed against the sides of the cylindrical part. Using the built-in guide line, you draw a straight line along the surface. This line passes through the center of the circle.

By repeating this process from a different position and drawing a second line, the intersection of both lines marks the exact center of the cross-section.

How it works

1. Press the tool against the cylindrical part so both inner faces touch

2. Draw a line using the guide slot

3. Rotate or reposition the tool and draw a second line

4. The intersection point is the center

Perfect for drilling, cutting, or marking round materials with confidence :)
