PH60 Rev.3 is a 60% tri-mode mechanical keyboard kit with an FDM 3D-printable case and the PH60 Rev.3 Multi PCB. This revision switches to the NRF52840 MCU with Bluetooth 5.3 and Nordic 2.4 GHz proprietary protocol (TBD), runs ZMKs firmware (our fork of ZMK), and redesigns the case for wireless use and multi-layout compatibility.
- Nordic NRF52840 MCU, Bluetooth 5.3 + 2.4 GHz (TBD).
- ZMKs firmware with ZMKs Studio for real-time keymap editing.
- Multi-layout support — ANSI / ISO / WK / WKL / HHKB, plus split spacebar: 6.25u → 2.75u + 1u + 2.5u, 7u → 3u + 1u + 3u.
- Battery powered, built-in battery connector.
Note on ANSI/ISO variants: Rev.3 currently only ships the Multi layout PCB. The ANSI PCB in this repo is an early prototype with a fundamentally different design approach — there is no standalone ISO version. We may develop dedicated ANSI/ISO variants based on ZMKs in the future.
- Designed for FDM 3D printing — printable on any printer with a bed ≥ 256 × 256 mm, no supports required.
- Magnetic quick-release latches — tool-free disassembly.
- O-ring gasket plate mount — firm, crisp feel without foam.
- Modular battery tray and magnet drawers, fits up to 100 × 50 × 5 mm LiPo and 10 × 5 × 5 mm magnets.
- Locking holder for wireless receivers, compatible with most commercial 2.4 GHz receiver housings.
- Multiple outer case variants: Standard, WKL, HHKB (6u/7u), and split backspace options.
- Plates available for ANSI, ISO, WK, HHKB (6u/7u), LS64, EC60, and split-key variants.
- More layouts added over time.

The case prints well with default FDM settings. Recommended parameters for best results:
| Setting | Recommended | Notes |
|---|---|---|
| Filament | PLA or PETG | High-temp materials increase warp risk |
| Layer height | 0.2 mm | Model designed around 0.2 mm |
| Wall count | 2 walls | — |
| Infill pattern | Gyroid | — |
| Infill density | 15% | — |
| Wall generator | Arachne | Improves print speed |
| Accurate outer wall | Enabled | Reduces visible layer lines |
| Support | Off | Designed for supportless printing |
Make sure the bed is leveled and clean before printing. Use adhesive on long parts like the top cover to prevent warping. Sand and clean prints for a better finish.
| Item | Qty | Notes |
|---|---|---|
| 3D printed case parts | 1 set | PLA or PETG recommended |
| PH60 Rev.3 Multi PCB | 1 | Pre-soldered SMD components |
| MX-compatible switches | 61+ | Varies by layout |
| Keycaps | 1 set | Compatible with 60% layout |
| LiPo battery (optional) | 1 | Recommended: 100 × 50 × 5 mm, Molex 1.25 mm connector |
| Magnets | 8 | Recommended: 10 × 5 × 3 mm, N52 |
| Silicone O-rings | 8 | OD 9 mm, cord 1.5 mm |
| Silicone anti-slip pads | 4 | Recommended: 20 × 10 × 2 mm |

Q: Which 3D printers can print the Rev.3 case? A: Any FDM printer with a bed ≥ 256 × 256 mm that can print PLA or PETG.
Q: Which layouts does the Rev.3 case support? A: ANSI, ISO, HHKB, WK, WKL, LS64, and EC60 (NIZ electrostatic capacitive). Plate designs are continuously updated.
Q: Why is there no dedicated ANSI or ISO PCB? A: The early ANSI prototype has a fundamentally different design from the Multi PCB. We focused on Multi to support all layouts with a single board. Dedicated variants may come later based on ZMKs.
Q: What battery and magnet sizes are supported? A: Up to 100 × 50 × 5 mm LiPo battery. Magnets: 10 × 5 × 3 mm (N52 recommended). The battery tray and magnet drawers can be modified for other sizes.
