Beogram 4002 (5513) Remote Control: Final 3D Printed Part Added

I finally got around to get the final 3D printed piece for my Beogram 4002 (5513) remote control system: This part plugs into the 10mm orifice of the remote control receiver board and allows the bolting down of the board using one of the four screws that hold the main PCB in place. Here is a picture of the part (with the screw inserted):

When installed with the remote control board the original screw can be used to bolt it down. The cylindrical feature is just long enough to not force the remote board onto the component pins sticking out from the main PCB of the Beogram, while generating a stable fit of the board. Here is a picture of the part inserted and bolted down:

This concludes my design of the mechanical aspects of the remote system. I am planning to make a couple changes to the firmware of the microcontroller to further streamline the remote operation.
