Valve published STP, STL, and engineering diagram CAD files for the new Steam Controller and Puck under CC non-commercial license, continuing a pattern from Steam Deck and Valve Index releases.
Key Takeaways
Files cover external shell surface topology only; includes keep-out zones showing areas that must stay uncovered for signal strength.
License is CC non-commercial with attribution and share-alike; commercial accessory makers can contact Valve separately to negotiate terms.
Valve has released CAD files for Steam Deck, Valve Index, and the original Steam Controller previously, so this is consistent practice.
Intended use cases include skins, charging stands, grip extenders, and smartphone mounts for the Controller and Puck.
Hacker News Comment Review
Commenters noted the released models contain only the outer mold line with no internal features, limiting utility for shell replacement or structural modification work.
Accessibility use cases drew positive attention: 3D-printed custom controllers for disabled players could fill a gap that commercial adaptive controllers price out of reach.
Scalper frustration dominated stock discussion, with one commenter reframing it as an underpricing problem rather than a scalper problem.
Notable Comments
@hydrogen7800: outer shell only, no internal geometry – limits real modification or replacement use.
@poisonborz: flags Steam-only controller dependency as a quiet walled-garden move despite standard layout.
@nkallen: shared a Plasticity web viewer link for the model so anyone can inspect it without CAD software.
