Hole Sizing (for calibration and screw hole estimation)

thingiverse

Because there needs to be extra room for mistakes when 3D printing, and these margins can change from one printer to another. I create this chart to figure out what size holes I will actually need in my models if I want a hole big enough for a screw to fit through, for example. It's arranged in a grid. The X-axis shows increases of 0.1mm, while the Y-axis shows increases of 1mm. For instance, the first two rows are... 1 1.1 1.2 1.3 1.4 1.5 1.6 1.7 1.8 1.9 [mm] 2 2.1 2.2 2.3 2.4 2.5 2.6 2.7 2.8 2.9 [mm] ... and so on. Enjoy.
