## CAD (KiCad official)

- Symbol: `SWXSBBCVE0-12.000000`
- Footprint: `Crystal:Crystal_HC49-4H_Vertical`
- 3D model: HC-49S (KiCad packages3D, STEP)
- 3D model files: `swxsbbcve0-12-000000-etched.step` / `swxsbbcve0-12-000000-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `swxsbbcve0-12-000000.step` / `swxsbbcve0-12-000000.glb` are the bare package body.
