Objective 2 amplifier case - JDS Labs

cleaned up the files for the JDS Labs objective 2 amplifier kit in order to make a case with a better fitting faceplate no lip around the case and made a volume knob that should fit as well as added some tolerance for the PCB to slide in better and made a rear plate to prevent pushing the PCB out the back of the case.

Important to note that the holes for the screws in the case need to be drilled out to fit an M3 screw but this should also allow for more flexibility in what screws you can use
