Both faces are built from 5mm MDF with a 2mm styrene covering.
Attached is a CAD file containing the size and dimensions of both faces. The MDF is cut to a slightly different size on the control side as it is used to stop the dials falling within the shell.
The easiest way to cut is by a laser cutter using the attached CAD file but if one is not available the attached files can be used as a guide as long as the control panels are cut accurately and the round discards are kept as they will be used to create the radios dials in later stages.
The speaker holes are wholly aesthetic but some are required to avoid an echo distortion.
Once created these faces can then be held together using a 'hard plastic' adhesive.
