Unlike the traditional center finder this one is designed to find the center of equilateral triangles. I made it for a special job where it was necessary to drill holes in the exact center of a bunch of them. Tap the small hole M3 and bolt them together.

-Added a second file with optional blades: one for vertical and one for horizontal marking. I slotted the blades so they can be adjusted more too.
