Sofle V2 Handwired Case (RJ9, Pico, no OLED/encoder)

I used AI (Claude with the Autodesk Fusion 360 connector) a lot when changing this design. Firmware and docs are in the GitHub repo. Changes from the original: - No OLED window or encoder holes

- RJ9 jack instead of TRRS, so plugging in can’t short anything

- Legs in the frame hold the Pico and the jack, so you don’t need screws or headers. The USB-C cutout lines up with the board

- 3 mm taller, to leave room for wiring

- Switch plate and frame are one body, with 5 legs under the plate so it doesn’t flex

- M3 hardware instead of M2

- Magnet pockets for a detachable wrist rest

Printing: - Most filaments should be fine. I used PLA with 0.4mm nozzle, 0.12mm layer height

- Use supports

- Wrist rests printed at thick layers on purpose, for a stepped look. Tune this to your liking

- STL and 3MF files are in print orientation

Parts (per keyboard): - 58× MX-style switches (I used Outemu Lemon v3 silent)

- 2× YD-RP2040 (Pico pinout, USB-C)

- 2× CONNFLY DS1132-01 RJ9 jacks + a 3-wire RJ9 cable

- 58× 1N4148 diodes, 1 mm bare copper wire for the rows

- 10× M3 heat-set inserts and screws

- 6×1 mm magnets

- 6x1 mm rubber feet (8x)
