Michael's Calibration Matrix

This is a validation / calibration matrix to rule them all. It builds upon the famous examples and tries to improve on them and combine the different strengths.

It contains exposure-triangles - like the Phrozen validation matrix; cones supported by differently sized supports - like Tableflips's Cones of Calibration; checkerboard, depth features and slits - like Ameralab's Town and a whole lot more.
It uniquely contains two breakout parts: a 3 mm ID tube that fits onto a protruding 3 mm cylinder and an M3 nut - which may fit the M3 screw next to it - depending on printer resolution and exposure.

Here are the features explained:

- All important feature dimensions are marked on the part! All features have meaningful metric dimensions. Deviations are immediately obvious.

- For simple resolution and exposure test - just stop the print after 1 - 1.5 mm and save time!

- XY-resolution combs and 45° tilted comb.

- Calibration cones: only the right most cone should fail mid-p
