What it does
- Larger opening catches bigger circles so you find dead centers faster
- Thickened design stays rigid under pressure so your marks stay accurate
- Built-in support prevents sagging so the tool works true every time
- 3D-printed on demand so you get exactly what you need when you need it
You need a center finder that does not wobble or bend when you use it. This 3D-printed workshop tool gives you a solid, reliable way to mark the dead center of any circle. The enlarged opening lets you work with bigger circles than standard finders. The thickened walls keep everything rigid, so your center marks come out clean and precise.
The design includes a small support brace that stops the tool from sagging under use. You just place it on your workpiece, align your pencil or marker through the opening, and mark your point. Works on metal, wood, plastic, and more. Made on demand in the USA so you only pay for what you order.

What it is made of

Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
