Not Yet Built

These don't have a case yet:

• Standalone case for ESP32-WROOM with confirmed reader support. Poseidon's case above supports the WROOM form factor but the reader compatibility (PN5180 vs PN532) isn't explicitly stated. A case with explicit reader-fit confirmation would still be useful.
• Keypad cutouts (3x4 matrix). None of the existing cases include a keypad opening. A remix of any standalone case above would work.

Design Guidelines

• Material: PLA or PETG, 0.2mm layer height, 15-20% infill.
• Antenna placement: NFC reader antenna as close to the scanning surface as possible. Avoid thick plastic layers between the antenna and the tag.
• Mounting: Both desk-standing and wall-mount options where possible.
• Access: USB port accessible. A slot is easier to use than a round hole.
• Ventilation: A few vent slots — the ESP32 runs warm.
• Several existing cases include CAD source files (STEP, Fusion .f3d). Remixing is fine.

How to Submit

Enclosure designs live in the usermods/ directory of the scanner repo.

1. Fork spoolsense_scanner.
2. Create a directory under usermods/ (e.g., usermods/my_enclosure/).
3. Include:
   • STL files (oriented for printing).
   • STEP or .f3d source so others can remix.
   • Photos of the printed result if possible.
   • A README.md with print settings and assembly notes.
4. Open a PR targeting main.

Each contributor owns and maintains their mod. See the usermods README for details.

If you don't want to open a PR, open an issue with photos and download links instead.
