The Typeractive Corne aluminum case is designed specifically for our Choc-spaced PCBs. A standard Cherry MX Corne PCB (3.5 spacing) will not fit properly in our Choc aluminum case, since the switch spacing and plate alignment are different.
If you’d like to use MX switches, you’d need an MX-compatible case/plate, not the Choc version we make.
If you’re aiming for an aluminum case build, you’ll want to match the case and plate to the same switch spacing as your PCB (Choc-to-Choc, MX-to-MX).
👉 Do you have the Corne Wireless kit from us, or are you working with a different PCB? That way I can point you to the right compatible case options.

i'm using the v3.5 cherry mx corne pcb from boardsource

Got it — thanks for clarifying! Since you’re using the v3.5 Cherry MX Corne PCB from Boardsource, that PCB uses standard MX spacing (19mm), while our Typeractive Corne aluminum cases are designed for Choc spacing (18mm).
That means unfortunately, our aluminum case will not fit the Boardsource MX PCB — the plate alignment and cutouts won’t line up correctly.
If you want an aluminum case for your v3.5 MX Corne, you’ll need to source an MX-compatible aluminum case or plate. Boardsource and a few community makers sometimes offer those options specifically for MX Corne.
✅ In short:
- Boardsource Corne MX PCB → MX-compatible case/plate
- Typeractive Corne Wireless (Choc spacing) PCB → Typeractive aluminum case
Would you like me to suggest some places where the MX-compatible aluminum Corne cases are usually available?

Awesome 👍 — here are your best bets for MX-compatible Corne aluminum cases/plates for your v3.5 Boardsource PCB: - Boardsource – They sometimes stock cases/plates made specifically for their Corne PCBs (MX spacing). Since your PCB is v3.5 from them, their plates/cases will be a guaranteed fit.
- MechMarket (Reddit/Discord) – The Corne is super popular, so people often sell aluminum cases or group buy extras there. Search for “Corne MX case” or “Corne aluminum plate.”
- P3D Store – They’ve done Corne cases in acrylic and aluminum variants in the past, sometimes with MX support.
- Custom/local makers – A lot of small CNC shops or hobbyists cut Corne cases on-demand, and you can usually ask for MX spacing specifically. Designs are often based on the open-source Corne files, but double-check they’re MX dimensions, not Choc.
👉 Tip: Always confirm with the seller that the case/plate matches 19mm MX spacing, since many shops default to Choc (18mm) because of how common wireless Corne builds have become.
Would you like me to also link you the official open-source Corne MX plate file so you could get it cut at a local shop or online CNC service if you can’t find a ready-made case?

Perfect! The Corne keyboard is fully open-source, and you can find the design files (including MX plate and case files) in the official GitHub repo:
🔗 Corne Keyboard GitHub Repository
Inside you’ll see:
- plate files for both MX (19mm) and Choc (18mm) spacing
- case files (usually acrylic layers) that you can modify or get CNC’d into aluminum
- DXF/SVG formats that can be sent directly to a laser cutting or CNC service
👉 If you take the MX plate file (look under plate/ in the repo) to a local metal shop or an online cutter (Ponoko, SendCutSend, or similar), you can have an aluminum MX plate made that will fit your v3.5 Boardsource PCB. From there, you can either pair it with standoffs/acrylic layers or commission a full CNC case.
Do you want me to point you to the exact file path for the MX plate in the repo, so you don’t have to dig for it?
