I'm needing 6 of the attached plate machined for some prototypes.

They're a 35mm square, with a flat sided circle in the center for locating a connector, and four 5mm bolt holes.
Plate thickness isn't critical but something in the region of 1 to 3mm is needed (round 2mm is probably best), and provided the bolt hole positions are marked, I can drill them myself.

The main bit I need done is the connector mounting hole.I
've drawn it with perfect internal corners, but for machining, it can be undercut into the circle by upto a mm (anymore and the sealing o-ring won't be effective), as I'd like the straight edge to remain untouched (it helps with stopping the connector from spinning).

The connectors are Bulgin PX0412 series, and I can supply a connector if needed to check fit.
