they tend to release 3d models of their stuff so that modders and companies can make replacement parts/cases real easy. someone will have different buttons ready to go real fast i bet. and valve usually doesnt care if you open your stuff up, replacing that shouldnt void it. although i get if you think thats too much effort, just sayin it should be easy.

just for neatness sake, heres the pages where they released the straight up CAD files for both.

they even released the steamdecks CAD files before it even came out so people could 3d print/make cases preemptively. im sure as soon as the final design for the new steam controller is set in stone they will release one for it as well.
