Oakley BXTR jaw replacement

[f1zza]

Hi, I have a custom Oakley BXTR (picture as example - these are not mine) and need to change the jaw.
Have contacted Oakley support who say that they dont sell these. Cant find any damaged ones online that I can use the part.
A mate suggested 3d printing it but i dont have the STL file for it.
Any recommendations on what I can do?

Let me know if you are able to source one as I need on as well. Thank you.

Hi, I couldn't find the file.
I even purchased a knock off from AliExpress but the parts don't match unfortunately
