Can you guys please add a horizontal size compensation to the program? It is the one thing that seems missing. You just need to do an erode or dilate on the slices before saving - which you can do with OpenCV or ImageMagik. Between 1 and 3 pixels seems good for any resin I have tried.
This is not the same as scaling because this ring gauge and pin set was printed at the same time, and scaling would make them all grow larger or smaller. What is needed is an erosion.
