I needed to adjust my door strike plates due to house settling. Instead of filing away the metal ones that were previously installed, I decided to make the file which can be bent to match the door with a heat gun. 

A DXF file is included so that the part can be laser cut out of compatible materials.

I haven't tested it, but the CutTongue file (in theory) might make it easier to perform the sharp bend of the interior latch hole.

I printed this out of PETG, but any semi rigid material should be fine.
