  "description": "Modeled by an AI agent from practice drawing MPD121 by Studycadcam (blog.naver.com/studycadcam). A shallow open-top tub with an obround (stadium) footprint: outer plan 78.74 mm long x 76.2 mm wide (end radii R38.1, 2.54 straight middle band), 38.1 mm tall, uniform 2.54 mm wall/floor thickness. Two Ø6.35 mm through-holes drilled through the floor centered at (X = ±25.4, Y = 0), spaced 50.8 mm apart on the long axis. Stated drawing dimensions (78.74, 76.2, 38.1, R38.1, 2.54, 50.8, Ø6.35) are modeled and verified against the finished geometry. Disclosed simplifications: the two \"M4\" tapped blind holes on one end wall are OMITTED (this modeler has no thread-cutting primitive, and the 13 mm depth callout would need a locally thickened wall boss beyond what the drawing shows explicitly); the R2.54 top-outer rim blend is OMITTED (small edge treatment).",
