How It Works

3D printers have inherent tolerance (typically 0.1-0.3mm). Holes print smaller than designed, shafts print larger. For a sliding fit, add 0.1-0.3mm to hole diameter. For press fits, reduce the gap or add slight interference. Always print test pieces to calibrate your specific printer.
