id take the reset button off and try to get that 3d scanned and printed. then modify the 3d print so it can work somehow.

I think that's called a (push) button cap. There's a vast selection. Try if the reset button cap fits the turbo switch. If it does measure the cap and click through hundreds of offers until you found the closest approximation. 👍

I finally ended up buying a AT front face plate and other accessories for only $23. Most of which I can reuse in other projects. I took the Turbo button off of the face plate and put it on my Aopen case. It matches perfectly!
