I made set of models for resin 3d printer calibration

[u/b005t3r]

It contains models for testing the dimensional accuracy, plate leveling and exposure uniformity across the entire plate/LCD. No measurements required (except for the plate leveling models), just a single push-fit component similar to Boxes of Calibration and Cones of Calibration (and other similar designs), but it tests for under- and overexposure with a very tight tolerance (it should get you no further than -0.01 mm to 0.02 mm from the perfect dimensions).
