Squircle Calibration Cube

SUMMARY

20x20x20mm calibration cube/circle/thing that will highlight issues such as:

- X/Y/Z/E step miscalibration - all axis should give an accurate reading of 20mm when measured with calipers. (Use rounded section for X/Y measurement. Z axis is also filleted to allow accurate measurement without interference of other issues such as linear advance miscalibration etc)

- Inadequate cooling on lettering overhangs - small overhang sections should be sharp with minimal 'sag'.

- Linear Advance miscalibration on the squared corners - corners should be sharp without any 'bumps'

- Ghosting/ringing - sharp lettering and dedicated dimple sections should show little to no ghosting)
