On July 3, 2026, Valve published the full "Inkterface" project (previously codenamed "Mango Frunk") on the Steam Hardware GitLab instance, giving anyone with basic electronics skills the ability to build their own e-ink faceplate for the Steam Machine . Here is exactly what was released and why it matters.
What Valve Open-Sourced
The open-source package includes everything needed to fabricate and assemble a functional e-ink front panel :
3D-printable CAD files (STP/STL) for the faceplate shell and mounting bracket
Full bill of materials (BOM) listing every required electronic component
ESP32 firmware and flashing instructions for the microcontroller that drives the e-ink display
PDF assembly instructions and a video tutorial covering the complete build process
An AppImage driver (or instructions to self-compile it) — Valve said it plans to release an official driver later, but in the interim users compile their own

Bluetooth (BLE) connectivity — the finished panel connects wirelessly to the Steam Machine
The display is battery-powered and can show live hardware stats (CPU temperature, GPU temperature, fan speed) or custom images .
From Internal Prototype to Free Community Release
Valve first showed the e-ink faceplate in November 2025 as a "concept" and explicitly stated it was an internal testing prototype that would not be sold . The standard Steam Machine ships with a plain magnetic faceplate; the e-ink version was never slated for retail .
On July 3, 2026 — eight months later — Valve reversed course and open-sourced the entire project instead of selling it . The company will not manufacture or sell the Inkterface itself; anyone with a 3D printer, an ESP32 dev board, an e-ink panel, and basic soldering skills can build one .
How This Fits Into the Third-Party Accessory Ecosystem
Valve has signaled a broad open-hardware strategy for the new Steam Machine family:
The base faceplate is magnetically attached and tool-less, making it trivially swappable .
Valve has released CAD files for standard faceplates so anyone can design and 3D-print custom covers .
The Steam Controller 2 (released May 2026) also got full CAD files under a CC BY-NC-SA 4.0 license just days after selling out, including STP/STL files for the shell and wireless Puck .
Third-party makers are already stepping in. Accessory company Jsaux is reportedly working on a commercial e-ink faceplate of its own .
This is a clear pattern: Valve declines to mass-produce an accessory, open-sources the design, and lets the community and third-party ecosystem fill the gap.
Valve's Current Hardware Pipeline
Hardware
Status
Timeline
Steam Machine (2026)
Launching this summer; confirmed by Valve in June 2026
Ships before end of August 2026
Steam Frame VR headset
Confirmed for summer 2026 alongside Steam Machine ; successor to Valve Index
Steam Controller 2
Released May 4, 2026; sold out in 30 minutes
Already live
Steam Deck 2
In active development; no release window committed
Earliest credible estimates: 2027 at the earliest, pending next-gen AMD APU (Medusa)
Key nuance on Steam Deck 2: Valve designer Pierre-Loup Griffais stated in April 2026 that the company is "hard at work" on it but declined to give a launch window . Multiple sources report that a truly next-gen APU (AMD Medusa) won't be ready until 2027, making a 2026 launch extremely unlikely .
The Bottom Line
The Inkterface open-sourcing is a textbook example of Valve's current hardware philosophy: ship a base product with a modder-friendly design (magnetic faceplate, released CAD files), let a prototype circulate internally, and then donate the entire engineering package to the community rather than entering the accessory business itself. This mirrors the Steam Controller 2 CAD release and creates a direct runway for third-party accessory makers like Jsaux. Meanwhile, Valve's main hardware push for 2026 is the Steam Machine and Steam Frame VR headset (both shipping this summer), with Steam Deck 2 still likely two or more years away.
