Just curious, what was your CNC setup for those like? What tools/coolant/feedrates did you use, and how did you fixture them? That surface finish on your cuts (under the ano) looks really awesome, did you just go crazy with finish passes or do some sort of tumbled finish before anodizing?
HAAS MiniMill. Trim C350 coolant at 7% Brix, 4 streams high pressure flood. Lakeshore carbide 1/4" 3fl ZrN coated endmill. 10% Stepover. 6000 RPM. 120 IPM pocketing. 0.010 finish pass at 60 IPM. No tumbling or anything. Just a deburring knife on the edges.

We fixtured by just bolting it down to a fixture plate that we drilled and tapped with a few holes.
