OpenSCAD models for restoring and reproducing parts of the Juku computer. Technical dimensions and modeling details are in NOTES.md.
Note
This project is an experiment in creating medium-complexity 3D models with an LLM. The OpenSCAD code was written through Codex with almost no manual code edits.
The keycap has a dished top, rounded chamfered sides, a central spring rod, contact pushers, and side latches that clip into the switch housing.

The bottom part of the computer case includes the PCB opening and guide, leg mounting holes, and reinforced PCB support mounts.

The rubber legs are simple stepped push-in feet matched to the bottom-case mounting holes.
