K4306 Front panel cutout template

Does anyone know of where I can obtain a front panel cutout template? The diagram in the manual seems slightly off scale to be used, as it has to be accurate to fractions of millimeters.

Or can anyone else think of a good way of making a template? I know it would be easier if I had the PCB as a template, but that thought came a little late and it’s all soldered and working.

Thanks
