Are you talking like a cnc mill?
If so you can probably download a program with the coordniates for it but there are a few problems.
1. Finding a program for a reciever. Most companies probably dont want to just give you the prints for there stuff. They cant make money unless you buy ther stuff. If you have a reciever or know someone who owns one that you could borrow, you could get a micrometer,caliper, and a couple other measuring tools and make your own print. Than you just enter all the cordnates on to the program using the x y and z axe.
2. Im not sure but Idoubt you will find a cnc to rent. These are not small pieces of equipment. If you have material and design though you may be able to find a machine shop and hire them to build your piece. The machines are quite expensive, even for moderatly cheap ones you can pay thousands for even a regular vertical milling machine or lathe. It would be a lot more for a computerized cnc machine.
