Door hinge alignment tool

thingiverse

This is a screw hole alignment tool I made when replacing an interior door of the house. The new door didn't have any screw holes or cutouts for a hinge. I was able to cutout where the hinge goes but needed something to center the screw holes. Once you can position your hinges, use this to drill the hole locations with an 1/8" drill bit. Flip upside down and print. No supports required. I printed @0.02mm layer height but should work with almost anything.
