Can anyone here make me a centering gasket for an MT-G2 for a Jaxman Z1?

I’m in need of someone who can make a centering ring for a Jaxman Z1 flashlight to fit a 20mm star MT-G2. I need it to basically fit with the black ring that screws over the LED. I can’t use the XHP 50 ring that comes with the light for obvious reasons. If possible, I’d like it to hold the LED down as well so I don’t need to add holes to the pill to screw the LED down, or have to resort to thermal epoxy.

Hopefully somone has the means to 3D-print or fabricate a ring for me.

Thank you!
