Ah that's what they use for steering wheels IIRC (old one's I guess

)
Looks great Syno, looks like you made GoPro happy, how many cams are on there ?

I think the black part would be a good candidate for 3D printing but not the clear inner part.
As mentioned, Blanka has a complete button and promised to do the 3D scaling etc. but no harm if you give it a try too....no harm in comparing I guess.
My guess about the plexi bezel/CPO is simply that it was not up to European mistreatment. In Japan people seem to have (had?) more respect for the machines, or probably things from other people in general. Look at the flimsy coin-doors as used by Nintendo. Compared to the US and Euro coin-doors they are very thin and fragile and a breeze to break into. Yet in Japan they apparently were sufficient.
I guess it's the same with the bezel. I think in Europe people banged them and maybe even sat on them or at least lifted themselves with their hand on it....
Or maybe it was just sunlight ? I have no idea. I do know we'll have to replace them

The hardest part, as I understand from Etienne is that it is very hard (impossible?) to have the silver bands printed.
And that is pretty sad because that is what it makes special compared to the Bertolino version, where the silver bands are simply white.
