## CAD (KiCad official)

- Symbol: `APT2012EC`
- Footprint: `LED_SMD:LED_0805_2012Metric`
- 3D model: 0805 (KiCad packages3D, STEP)
- 3D model files: `apt2012ec-etched.step` / `apt2012ec-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `apt2012ec.step` / `apt2012ec.glb` are the bare package body.
