Edit the attached SCAD file to change the parameters of the strike plate. Left/Right width is measured from the side of the latch hole to the edge. The rest of the variables should be self explanatory measuring down the strike plate. This prints upside down so the smooth side is what you see when it's mounted. Reinforced in the latch holes.Printed at .2mm layer height. Works perfect at 50% infill. 70% adds some more weight to it but isn't necessary.
