To check my leveling etc. is correct I was going to print a wide and thin cube. My theory being that I should be able to spot any obvious separation of the layers.
Does anyone have any better shape that they print as a dry run?

Your calibration shape depends on what you want to calibrate on. Among the most popular:
- Benchy as a general "overall" test.
- Lattice Cubes for retraction/stringing and overall quality.
- Two pillars to test for stringing and temperature/cooling control.
- Spikes for retraction, stringing and temperature/cooling control.
- Bridges for cooling control.
- Cubes for sizing. They also allow seeing if the printer is skewed in X or Y.
- Circles, crosshairs, and squares of just a couple layers high to determine the correct center of the print area and measure sizing.
- Cylinders in each other to check the achievable resolution and clearance.
- Overhang tests to test just overhangs.
- Temperature towers for temperature and overhang.
- Impact1 & Bend & Tension test pieces for filament properties - if you have the setups needed.

2$\begingroup$ Great list, although one not mentioned is a calibration square to measure diagonals in order to test the skewness. This is typically a large square only a few layers tall. $\endgroup$ Commented Dec 20, 2018 at 17:29

$\begingroup$ Lots of useful stuff there. How doe the bridge to test cooling control work though? $\endgroup$ Commented Dec 20, 2018 at 20:10

$\begingroup$ @BanksySan If the bridge fails or sags too much, you need more cooling. $\endgroup$– TrishCommented Dec 20, 2018 at 20:33
