It's a shame you don't have access to your specific hole cutters any more but one trick I used to use when cutting holes for sub-Ds was to find a PC interface card of any kind / sort which had the right size of 'D' connector on it, temporarily remove the vertical metal backplate from it and use that as a kind of stencil with which to draw the desired outline for the cutout, including the positions of the holes for the screw posts, by running an inedible ink marker around the inside edge of the cutouts for the connectors and the screw post holes. Remove the plate and you have exactly the right outline marked on the housing and ready to cut out with the screw post holes marked at the correct relative spacing.

An old motherboard backplate, or one from a serial port card or multi i/o card should have at least one 25-way cutout which you can utilise in that way - for 15-way you'd need to find an old soundcard with a 15-way 'game' (joystick / MIDI) port on it.
