circular center-finding tool

This 3D-printed circular center-finding tool is designed to quickly and accurately locate the center point of round objects such as discs, pipes, or cylindrical parts. The adjustable sliding arms align evenly along the edges of the object, automatically guiding the marking line to the true center. Its lightweight yet sturdy construction makes it easy to handle, while the elongated slots allow smooth adjustment for different diameters. Ideal for woodworking, metalworking, and DIY projects, this tool demonstrates how 3D printing can create practical, precise, and customizable measuring aids.
