Valve Releases Steam Frame CAD Files, Documenting PCIe and MIPI Expansion Port

Summary
Valve published a hardware reference repository for the Steam Frame, giving modders STEP-format models for the headset’s core module, head strap and controllers.
The files are meant to speed custom accessory design by removing the need to measure or 3D-scan the hardware, while also mapping controller IR tracking LEDs so add-ons do not block them.
A front expansion port is also documented, exposing high-speed MIPI camera and PCI Express interfaces alongside a reference design in both KiCad and Altium.
The release extends Valve’s hacker-friendly approach as Steam Frame demand still exceeds supply, leaving some buyers on a waitlist while they plan modifications.
