## CAD (KiCad official)

- Symbol: `APT3216CGCK`
- Footprint: `LED_SMD:LED_1206_3216Metric`
- 3D model: 1206 (KiCad packages3D, STEP)
- 3D model files: `apt3216cgck-etched.step` / `apt3216cgck-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `apt3216cgck.step` / `apt3216cgck.glb` are the bare package body.
