A customer needed a machined shim was to fit between a stamped metal plate and the side of a melamine desk. The customer supplied the dimensions of the metal plate in DXF format, and a plastic shim was created to the exact size required. Note the recesses near the holes - this allows the shim to sit flush where the metal plate protrudes.
