The model was originally created in CAD.
I am attaching the following list of files.
.stl/.step, .fbx (low/high), .blend (low/high, low-high) _, 4k Texture.png _PBR Metal/Rough, base.color, metalic, normal, roughness., Baked maps (ao, curve, matid, normal, normalobj, position, thickness.)
*The model is one-piece and has no internal parts.
*The model is not an exact reproduction of the real prototype. It may have size errors.
