Valve releases Steam Controller CAD files so you can print your own shell
The Steam Controller 2 sold out everywhere within 30 minutes of going on sale May 4 — and Valve's response was to publish the controller's full CAD files two days later. The move hands anyone with a 3D printer the official geometry they need to make custom shells, grips, and covers, no legal grey area required.
What Valve actually released
The files — STP and STL models plus detailed engineering drawings — went live May 6 on GitLab under a Creative Commons CC BY-NC-SA 4.0 license. That means free to use for personal or community projects, with attribution and the same license attached. Commercial use requires a separate agreement with Valve, but the pathway exists.
The package covers external shell topology and surface geometry only. Internal electronics are not documented. The drawings do flag "keep out" zones — areas where structural changes would interfere with buttons, sensors, or internal components — which matters if you plan anything beyond a colour swap.
Valve's note alongside the release was direct: they want to see what the community builds.
Why this is useful right now
The immediate scarcity makes the CAD release more than a goodwill gesture. At $99 (£85 in the UK), replacing a cracked or damaged shell via a 3D-printed part is far cheaper than hunting down a second unit — scalpers were already listing the controller at two to three times retail within hours of launch, per VGC.
Official CAD access also cuts the dependency on donor units from the used-parts market. Shell repair goes from a grey-market scavenger hunt to a straightforward print job.
Beyond repair, the files open up genuine ergonomic customisation. The original 2015 Steam Controller built a dedicated following partly because enthusiasts adapted it for genres Valve never anticipated. Valve is explicitly inviting the same thing here — and this time with official geometry rather than reverse-engineered approximations. Accessory makers are already moving: PC Gamer reports dbrand and JSAUX both have projects underway.
The bigger picture
PlayStation and Xbox both lock down hardware IP tightly. Valve releasing official design files — covering not just the Steam Deck but now the Controller 2 as well — builds a consistent record of hardware openness that neither Sony nor Microsoft can match. For anyone who just missed out on launch stock, it at least means the controller you eventually find won't be a dead end if it takes a knock.
The Steam Controller 2 is sold exclusively through the Steam Store. No third-party retail availability has been confirmed in the US or UK.
