This center finder is designed for locating the centers of round objects such as boards or other materials (up to 400 mm Diameter), and it also works well for finding centers on drawn circles (up to 350 mm Diameter).
The center marking ruler is offset by 0.25 mm to account for pen thickness, at least to some extent. I found this very helpful and haven’t seen it in other designs.
The small triangle additionally helps with finding the centers of small circles with the same tool.
The two holes allow you to precisely mark two points of lines that intersect at the center.

Take your time when removing it from the print bed. I removed mine a bit too early, and it bent slightly.
