I'm afraid I don't have any orginal Naomi panels any more. The only Sega shape panel I have left is a Bishi Bashi panel and this is far thicker than a standard Naomi panel. Maybe someone else will be able to measure one for you.

Identical to the E3102171A but with a stud arrangement to a range of joysticks:
Seimitsu SE - Fits: LS-32/LS-32-01, LS-34/LS-34-01, LS-40/LS-40-01.
Seimitsu SE-P40 - Fits: LS-55/LS-55-01, LS-56/LS-56-01, LS-58/LS-58-01 and LS-60
Sanwa JLF-P-1 for the JLF
Mounting studs for the joysticks have increased to take into account the ~7mm spacers you'll need to use to achieve the correct joystick height.
I've taken as much care as possible to ensure all dimensions are correct and I've printed multiple scaled .dxfs off to confirm accuracy. I'm as confident as I can be without actually getting a panel cut and offering up overlays etc. I would appreciate feedback from anyone who gets one cut so I can update the model if required.

I'll be adding some custom Vewlix control panel .dxfs once I've finished designing them.
