When placing castors onto the bottom of a flight case, the default position reference is from the centre of the metal castor plate.
So if you were to position the castor 100mm x 100mm from the outer most corner anchor, when it comes to positioning the dishes on the case top panel you can use these measurements and offset one of them by the required value.
When placing the stacking dishes onto the case, change the 'measurement from' to 'centre' as shown on the video.
Then position the castor cups 100mm x 140mm from the case corner anchor point.
In this scenario the castor used has a 40mm offset from the centre of the mounting plate, to the centre of the wheel axle. So the wheels will now stack on top of another identical case.
