Valve just yeeted the full CAD files for the Steam Frame out into the wild on their GitLab repo, and the modding gremlins are already loading up Fusion 360 like it's Black Friday. Light blockers, head straps, battery housings, facial interfaces — the whole kit is fair game now, plus docs on that front expansion port with its PCIe Gen4 lane and MIPI camera hookup. PC Gamer called it out loud: someone’s probably already mocking up cat ears for this thing, and honestly? Based.

This isn’t Valve’s first rodeo with the open-hardware drip — they dropped files for the Deck, the old Steam Machine, and even the Controller. The license is CC BY-NC-SA 4.0, so non-commercial prints and tweaks are green-lit while big corpos still gotta hit them up for the bag. Hackaday noted the IR LED positions and reference KiCad/Altium designs for the port, meaning third-party powered accessories (like that Arcturus Vision RGB cam already floating around) just got way easier to build. X is already lighting up with people posting the GitLab link and hyping the first STL drops.

Community chatter on the feeds and in the replies is peak chaos: folks on the 2027 reservation waitlist are straight-up saying they’ll just 3D-print their own comfort fixes while they wait. Valve’s own upgraded strap with hot-swap batteries and off-ear speakers is still “coming soon,” but the CAD drop basically says “go wild, we trust you.” Light blocker too tight? Print a new one. Hate the stock strap? Make a better one. This is the Valve we stan — handing over the blueprints instead of gatekeeping the hardware.

The repo’s live right now, models are STEP and STL, and the expansion port PDF is sitting there like an invitation. Mod scene’s about to cook. Go print something unhinged.
