The file 'Metric Center Finder With Sized Inserts 3D Printer Model' is (stl) file type, size is 306.3KB.
As quite a lot of people have requested in the comments of thing:5182359, I just re-built the center finder in metric. It also seemed useful to me to being able to replace the center part both for other drill diameters as well as when they're worn out instead of replacing the whole part.
The initial "Baseplate" is 20cm from pin to pin. "Baseplate_small" is sized 10cm.
The offset between two outer or two inner edges is 4mm for the large one and 2mm for the small baseplate, the offset between an outer and an inner edge is 2mm and 1mm respectively.
I have not yet printed this myself, so if the tolerances are off or if you happen to need another drill diameter, drop a comment.
