Better 3D Printed Gears

This is how I have found a way to 3D print decent spur gears.
Have you printed gears and then needed to file out the spread where the part has been set on the printer bed? Do you have a hard time trying to release the part from the bed without damaging the gear teeth?
The first thing I did was to modify the original gear file, imported from the McMaster site in Fusion360, by creating a clearance step underneath just the gear teeth that would come into direct contact with the printer bed. This was achieved by drawing 2 circles on the bottom face of the part to create a tyre type area that covered the teeth and extruded into the part by 0.5mm, thus making a step that cleared the bed.
I then printed the part using the 'Support' Feature in Cura and setting it to 'Touching Buildplate. This allows the actual teeth to be printed on top of the support to their correct shape and eliminating the spread factor.
I next created a triangular wedge shape on the side elevation of the teeth startin
