  "prompt": "This part resembles a U-shaped bracket or channel with a rectangular base and two vertical walls extending upward. Begin with a rectangular base plate measuring 1.0547 mm by 0.7882 mm with a thickness of 0.0625 mm, positioned in the XY plane. From this base, extrude two vertical rectangular walls that extend upward approximately 0.75 mm in height - one wall positioned along the left edge of the base and another along the right edge, creating the characteristic U-shaped profile. Each vertical wall has a thickness of about 0.0666 mm and maintains the same width as the base dimension (0.7882 mm), forming a symmetric channel structure. The resulting geometry has 19 planar faces and creates an open channel that could serve as a guide, bracket, or mounting feature. Orient the longest axis along X.",
