3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`b57451v5103h062.step`	40 KB	You want the bare part, or you mark your own boards.
`b57451v5103h062-etched.step`	2.6 MB	You want the part with `B57451V5103H062` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 629 faces against 26 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
