Hi Alan,
I'm glad that you did quite impressive piece of art using your CNC-machine.
However, I just checked the 3D model of the fuel cap I sent you before and I figured out it's the wrong scale. Sorry for that and hopefully it didn't cost you much time and money so far (and also to anyone who used my file with wrong scale)!
I made this 3D model after a request of IKR where he asked me to make it 5" diameter, or 127 mm. Using a high-res photo of Aventador as reference, it seems that
the correct size of this fuel cap is approximately 160 mm diameter (6.3"). I sent you the updated 3D model to your e-mail.
Regards,
Bobi
