XYZ 20mm Calibration Thing
thingiverse
The calibration cube gets a variation that's easy to build and use. Each opposing face is exactly 20 mm apart, making it perfect for checking main axes (x,y,z) as well as diagonals. If your printer frame isn't a rectangle, you'll see some diagonals are too short while others are too long.
