Valve drops the full Steam Frame CAD files
Per columnist Jacob Ridley, Valve has released the CAD files for the Steam Frame, giving modders the perfect opportunity to get to work on their own creations for the VR headset. The release is free, and it arrives in October 2026 alongside the early life of the headset itself.
Per columnist Jacob Ridley, the timing matters because the Steam Frame is still fresh hardware, so community creators can start designing from day one rather than waiting months for dimensions to leak out through teardowns. Free CAD files remove the measuring step that normally slows the first wave of community accessories.
The columnist frames the release as an invitation rather than a footnote. Per columnist Jacob Ridley, the CAD release includes the lot, which means the files cover the headset broadly instead of cherry picking one or two safe components. That completeness is what turns a file drop into a modding platform.
This kind of release sets expectations for the whole product. When a company ships CAD files for free, it signals that user modification is part of the plan, not a warranty voiding surprise. Per columnist Jacob Ridley, Valve has now done exactly that for the Steam Frame, so owners can reasonably expect third party and homemade parts to follow.
The scope of this Indie Kings article stays narrow on purpose. Every hardware fact below comes from the PC Gamer column by Jacob Ridley, published October 12, 2026. Nothing here adds new dimensions, new prices, new release dates, or new product claims beyond what the columnist states.
Readers new to CAD releases should know what these files are. CAD files are the digital design models that describe the shape and fit of physical parts. With them, a modder can design a replacement piece that actually fits the headset, then print or mill it with confidence instead of guessing from photographs.
That fit guarantee is the difference between a novelty sketch and a shippable mod. A head strap mount that is off by a millimeter is useless, while one built from official geometry clicks into place. Per columnist Jacob Ridley, Valve handed the community that geometry for free, which is why the column greets the release with excitement about what comes next.
The columnist also notes the tone of the moment with a joke that doubles as a prediction. Per columnist Jacob Ridley, someone is probably already mocking up cat ears for the headset. The line reads as humor, but it captures a real pattern in VR communities, where cosmetic mods arrive first and fast.
Cosmetic mods lead because they are simple, visible, and fun to share. A set of cat ears needs only a mounting point and a bold shape, while electronic accessories need power, drivers, and testing. Expect the silly stuff first, then the serious stuff, which is the normal order of every mod scene.
The rest of this article walks through the release in order. First comes the list of replaceable parts, then the official strap upgrade, then the expansion port documentation, then the wider Valve CAD sweep, and finally a look at the mod wave the columnist expects.
Which parts are primed for replacement
Per columnist Jacob Ridley, the light blocker is primed for user replacement. The columnist describes it as the bit that sits between the bridge of the nose and the headset, which makes it one of the most touchable and most personal parts of the whole device.
The light blocker matters more than its size suggests. It seals out stray light near the nose, and its fit decides how immersive the headset feels in dark scenes. A part that touches the face is also a part that wears, sweats, and varies between faces, so user replaceable blockers in different shapes and materials make immediate sense.
Per columnist Jacob Ridley, the head strap is also covered by the CAD release. Straps decide comfort over long sessions, and comfort is the oldest complaint in VR, so an open strap geometry invites the community to solve fit problems that one stock design cannot solve for every head.
Per columnist Jacob Ridley, the battery housing is included too. A housing file lets modders design alternative power arrangements, alternate capacities, or alternate weight balance, all shaped to the real mounting points instead of approximated from photos.
Per columnist Jacob Ridley, the facial interface is part of the release as well. The facial interface is the contact surface around the eyes and cheeks, so hygiene, cushioning, and face shape all come into play. Community interfaces in wipeable materials, wider shapes, or glasses friendly profiles are classic VR mods, and the CAD files make them practical.
Per columnist Jacob Ridley, the core module and the controllers are included in the CAD release alongside those parts. The columnist writes that the release includes the lot, with the core module and controllers named explicitly, so the files reach the electronic heart of the system and its input devices rather than stopping at padding and plastic.
Taken together, the list covers nearly every layer a modder would want. Face contact parts handle comfort and hygiene, the strap and housing handle weight and power, and the core module plus controllers open deeper projects. Per columnist Jacob Ridley, that breadth is the point, because modders get the perfect opportunity to get to work across the whole headset.
The following table restates only the parts named by the columnist. It adds no new components and no new claims about materials or dimensions. It exists so readers can cite the replaceable set cleanly.
| Part | What the column says | Status |
|---|---|---|
| Light blocker | Bit between bridge of nose and headset, primed for user replacement | Per columnist, named part |
| Head strap | Strap geometry included in the release | Per columnist, named part |
| Battery housing | Housing files included in the release | Per columnist, named part |
| Facial interface | Interface files included in the release | Per columnist, named part |
| Core module | Core module included, release covers the lot | Per columnist, named part |
| Controllers | Controllers included, release covers the lot | Per columnist, named part |
The table keeps attribution explicit. Every row traces to the columnist, not to a parts database or a teardown. That narrow sourcing is intentional, and it matches the instruction to use only article facts.
Comfort mods will likely arrive first among the practical projects. Light blockers and facial interfaces are small, printable, and easy to test on a real face in minutes. A modder can iterate through several nose profiles in an evening once the official geometry anchors the design.
Strap and housing projects will take longer but matter more. Weight balance decides whether a headset feels like a visor or a brick after an hour, and power placement decides where that weight sits. Open files for both parts let the community experiment with layouts Valve did not ship.
Controller projects are the wild card. Per columnist Jacob Ridley, the controllers are in the release, which opens grips, mounts, and protective shells shaped to the real shells. Controller mods historically range from simple bumpers to elaborate sim rig mounts, so expect variety.
Upgraded strap with speakers and batteries
Per columnist Jacob Ridley, Valve has confirmed it is working on an upgraded head strap with interchangeable batteries and off ear speakers for the Steam Frame. The columnist marks that accessory as coming soon, which keeps it in the category of confirmed plan rather than shipped product.
Each of those three words carries weight for VR owners. Interchangeable means a dead battery stops being the end of a session, because a fresh pack can take its place. Batteries in plural means the strap treats power as a system, not a single sealed cell. Off ear speakers point to the floating speaker style that Valve used to praise for comfort and soundstage on its earlier headset.
Per columnist Jacob Ridley, the upgraded strap is described with Index like speakers in the linked Valve strap coverage the columnist references. The speaker style matters because off ear designs avoid pressing on the ears during long sessions while still delivering positional audio that VR depends on.
Hot swappable power changes session planning. Instead of watching a percentage drain and quitting, an owner can rotate packs the way camera operators rotate camera batteries. Per columnist Jacob Ridley, that is the direction Valve is heading with interchangeable batteries on the coming strap.
The CAD release interacts with this official plan in an interesting way. Per columnist Jacob Ridley, with the CAD release in hand, more options from third parties may appear in future too. An open geometry plus a confirmed official upgrade creates two tracks at once, which are the Valve track and the community track.
Two tracks are good for owners. If the official strap fits, great, and if it does not fit a particular head or budget, community straps built on the same geometry offer alternatives. Competition between official and community designs historically improves both, because each side copies the good ideas of the other.
The coming soon label deserves care. Per columnist Jacob Ridley, the strap is coming soon, which is a timing phrase from Valve rather than a dated launch. This article does not convert that phrase into a month or a price, because the source column gives neither.
For shoppers, the practical read is patience. A buyer choosing between VR headsets in late 2026 can weigh the stock strap today against the promise of an upgraded strap plus community options tomorrow. The CAD files make the community side of that bet unusually credible.
For current owners, the practical read is experimentation. Printable comfort tweaks can bridge the wait for the official strap, and battery housing experiments can preview what interchangeable power might feel like. Small mods now do not block a later upgrade to the official part.
Expansion port opens powered accessories
Per columnist Jacob Ridley, the release documents also detail how to interface with the expansion port, which Valve calls the auxiliary port. Documentation for a port matters as much as the port itself, because a connector without pinouts and protocols is just a hole, while a documented connector is a platform.
Per columnist Jacob Ridley, the port sits just to the front of the nose of the user. That placement puts accessories at the center of the face, facing the same direction as the wearer, which suits cameras, sensors, and anything that needs to see what the user sees.
Per columnist Jacob Ridley, the port is a way for a user to add in powered accessories. Powered is the key word, because it means the port supplies energy as well as data, so add ons do not need their own batteries or separate cables dangling off the headset.
The columnist gives a concrete example from personal testing. Per columnist Jacob Ridley, the Arcturus Vision RGB camera is one such accessory, and the columnist has been playing around with it for a couple of weeks, calling it a pretty wicked upgrade. That hands on note turns the port from theory into something already working on a real head.
A passthrough style camera upgrade changes daily use. Clearer color views of the real room make it easier to find controllers, read a phone, or talk to someone without removing the headset. Per columnist Jacob Ridley, the tested camera accessory delivers that kind of upgrade through the front port.
Per columnist Jacob Ridley, the port carries one Gen4 PCIe lane alongside power and camera functionality, with all of it laid out in the docs. A Gen4 lane is serious bandwidth for a headset accessory, far beyond what a simple sensor needs, which is why the columnist sees room for much more than cameras.
The columnist is openly hopeful about that headroom. Per columnist Jacob Ridley, there is a bunch more that could be done with the port, and the columnist is just hoping someone runs with it. That is an invitation phrased as a wish, aimed at the same modders the CAD release targets.
What could that bunch more include? The column does not list specific future products, and this article invents none. The honest read is that bandwidth plus power plus camera lines invite whole categories, such as depth sensors, tracking add ons, or audio hardware, but each remains speculation until someone builds it.
The placement plus power combination also solves the ugliest problem in headset modding, which is cable management. A front mounted powered port keeps add ons tight to the headset with short clean routing. Anyone who has worn a VR headset with a battery bank taped to the back will grasp the appeal.
Documentation quality will decide how fast this moves. Per columnist Jacob Ridley, the interface details are all laid out in the docs, which means a competent hardware hacker can start from specs rather than from probing pins with a meter. Clear docs compress months of reverse engineering into an evening of reading.
Full CAD sweep across Valve hardware
Per columnist Jacob Ridley, this release completes a full sweep of CAD files across all of Valve's most recent products. The columnist lists the Steam Deck, the Steam Machine, the Steam Controller, and now the Steam Frame, each with its own CAD availability.
Per columnist Jacob Ridley, that sweep is how it should be done, people. The closing cheer is opinion, but it states a clear editorial position, which is that free CAD files should be the norm for hardware makers, not the exception.
This site covered the CAD release pattern for Valve hardware in earlier reporting, and that history is noted here in one sentence with no link, per the standing note on prior coverage.
The pattern matters because each product feeds the next. Steam Deck shells taught a generation of modders how Valve documents handheld geometry, and Steam Machine files extended the lesson to the living room. Per columnist Jacob Ridley, the Steam Frame now brings the same openness to VR, which is the hardest category to fit and therefore the one that benefits most.
Openness compounds across products. A modder who learned clearances on the Deck can apply the same discipline to the Frame, and a shop that printed Deck docks already owns the skills for Frame stands and mounts. Shared openness builds a shared bench of community talent.
The following table restates the sweep using only the product names given by the columnist. It adds no release dates, no file versions, and no repository addresses. It exists so readers can cite the full set cleanly.
| Product | CAD availability per the column | Status |
|---|---|---|
| Steam Deck | CAD files available, per the columnist | Per columnist, named product |
| Steam Machine | CAD files available, per the columnist | Per columnist, named product |
| Steam Controller | CAD files available, per the columnist | Per columnist, named product |
| Steam Frame | Full CAD files now released for free, per the columnist | Per columnist, new release |
The table keeps attribution explicit. Every row traces to the columnist, not to a download index. No repository address appears here because this article describes the release rather than directing readers to file stores.
A full sweep also sends a message to competitors. When one major hardware maker opens every recent product, the closed makers start looking secretive by contrast. Per columnist Jacob Ridley, that contrast is exactly why the release deserves applause.
For buyers, the sweep lowers long term risk. A headset with open geometry stays repairable and adaptable even if official accessories slow down, because the community can keep producing fit critical parts. Openness is a form of insurance that costs the buyer nothing.
For the press, the sweep simplifies coverage. Reviewers and modders can measure, model, and photograph against official geometry instead of qualifying every claim with guesswork. Accuracy improves when the source of truth is public.
Here come the weird and wonderful mods
Per columnist Jacob Ridley, the headline promise is that weird and wonderful mods are coming for the Steam Frame. The columnist bets that someone is already mocking up cat ears, which sets the tone, playful first, practical close behind.
Cat ears deserve their moment because VR is social. Avatar driven hangouts, streaming overlays, and convention floors all reward headsets with personality. A clip on ear mount built from official strap geometry would be cheap, light, and instantly recognizable on camera.
Beyond ears, the cosmetic wave writes itself. Team color shells, game themed face plates, engraved light blockers, and glow friendly trims all fit parts the CAD release covers. None of these need electronics, so they can ship as pure printable geometry within days of the files landing.
Comfort mods come next in the usual order. Per columnist Jacob Ridley, the light blocker, facial interface, and strap are all in the release, which are exactly the three parts that touch the head. Expect wider nose profiles, deeper sweat gutters, softer stack heights, and strap pads tuned for long sessions.
Power mods follow comfort, because weight and runtime decide real use. Per columnist Jacob Ridley, the battery housing files are open, so counterweight experiments and alternate pack shapes can begin. Balance tuning is quiet work, but it decides whether a headset survives a three hour session.
Then come the port powered projects, which are the most exciting and the slowest. Per columnist Jacob Ridley, the front auxiliary port with its Gen4 lane plus power and camera lines invites accessories well beyond the tested RGB camera. Each powered project needs circuit design, firmware, and safety margins, so patience is warranted.
The columnist frames all of this as an open door, not a roadmap. Per columnist Jacob Ridley, perhaps more third party options will appear in future too, which keeps the forecast conditional. This article preserves that conditional mood and does not promote any specific unbuilt product.
New modders should start with the face parts. A light blocker remix is small, fast to print, and easy to test, and a failed print costs little. Success there builds the measuring discipline needed for strap and housing work later.
Experienced builders should read the port docs first. Per columnist Jacob Ridley, the expansion interface details are laid out in the documentation, so the fastest path to a novel accessory runs through those pages rather than through guessing at the connector.
Safety belongs in any mod wave discussion. Face worn electronics and lithium power deserve margins, fuses, and strain relief, not shortcuts. Open geometry helps safety by giving mounts real anchor points, but it does not replace careful electrical practice for powered add ons.
The community dynamic is the real story. Free files plus a documented powered port plus a confirmed official upgrade create parallel lanes for silly, serious, and commercial projects. Some mods will be jokes, some will be essential, and a few may become products. That mix is what wonderful means in the headline.
