How to reduce a circle carve

I have a lazy susan I am making using wood and resin. I carved a 1.5 mm slot into glossy melamine to insert some plastic to use as the form to pour the resin and contain it. Also using this as the baseboard for the cncrouter I am using to trim the output to be the perfect circle about 5 mm less in diameter. I also want to do the same with a roundover bit to make the outside 5 mm rounded. I thought the best way to do thyis is to run the attached project. and decrement the size of the circle. How can I do that and not have to output a new g-code and upload etc. is there a way to do that using some sort of addon or existing app ?Easel - 700 mm Lazy Susan 1.5 mm 2 flute cut 3mm deep

What would happen if you swapped to a larger diameter bit and ran the same program? You’d end up with a circle that is smaller by the difference between the two bits, right?

I could use the roundover bit too? not really so a new gcode but yes I guess I would get a circle that is less as per your solution. Of course I would need a larger bit to decrease it exactly to the size I want…

Have you looked into using the Easel app Offsetter (v2). You can change size of circle any amount. I use it to resize any design.
