Looks really nice! Just FYI most cnc’s don’t have a ‘finish oversize’ option. When designers are making the CAD they will typically design with tolerances in mind. The software doesnt know what dimensions you are OK with being over or undersized. Sometimes its even left up to the machinist at the machine to determine what offsets he wants to set on OD and ID cuts based on how his machine is cutting that day and the tools being used. Just keep it simple for now. Remember you can always take more off, but its a bitch to put it back on….if you can.
