I also didn't add the slot for the PCB, mostly because I wasn't sure of the size, and I didn't have the appropriate cutter lying close by. I have a couple thoughts on that.
hmm me too: a CNC lathe would do the trick. the slot is essential in one of the parts for access to the PCMCIA eject-button.

Yeah. At the complexity of the inside you have there, I don't see anything short of CNC that that could reasonably do the job. Those sharp inside corners are hard, but it looks like a single cutter pass can probably run past far enough to work if that direction were taken.
Not sure if you are looking for one but this reasonably-priced CNC kit machine seems to get good reviews on Amazon: https://www.bobscnc.com/collections/cnc-routers-engravers/products/e3-cnc-en... https://www.bobscnc.com/collections/cnc-routers-engravers/products/e3-cnc-engraving-kit
