Hmm, OK. If you want to do something similar it may pay to see if you can
find someone who will laser cut for you then, especially if you can supply
electronic source from a CAD program.

Back in NZ I had some adapter brackets done is stainless steel this way when
we wanted to put a DB25 connector where a Centronics connector had been. Was
a very reasonable price. They could do plastics and metal - except aluminium
(presumably goes molten enough to reflow back over the cut) which is why I
ended up with stainless steel.

Are you actually looking at a production item, or proof of concept product?
If the latter then you may be able to vacuum mould something in you oven at
home over a block of wood to get something good enough to show potential
customers, and act as a sample to take for quotes to mould
makers/manufacturers.
