## CAD (KiCad official)

- Symbol: `F12F12`
- Footprint: `Fuse:Fuse_1206_3216Metric`
- 3D model: 1206 (KiCad packages3D, STEP)
- 3D model files: `f12f12-etched.step` / `f12f12-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `f12f12.step` / `f12f12.glb` are the bare package body.
