Along with the recent stable Steam client update bringing full support for the Steam Controller, Valve also released the CAD files for modders.
This is great news for anyone who wants to “hack, mod, or design accessories for the Steam Controller and Puck” say Valve. What have they released? The “CAD files for the external shell (surface topology) of Steam Controller and Puck available for download under a Creative Commons license” which includes “an STP model of each, an STL model of each, and an engineering drawing with critical features/keep outs for each”.
You can find all the files on their GitLab.
I fully expect we’ll end up seeing some accessory makers design entirely new casing for the Steam Controller, just like we saw with the Steam Deck. We already have dbrand skins, but actual casing would be interesting to mod.
Valve continue to impress with their openness when it comes to their hardware.
