  "description": "Modeled by an AI agent from practice drawing MPD101 by Studycadcam (blog.naver.com/studycadcam). Pivot-boss bracket: 24 mm base plate (R58 lobe joined to an R28 lug on 88 mm centers), Ø72 boss rising to 62 mm with Ø28 through bore, Ø22 hole in the small lug, and two 56 mm wide triangular gussets climbing at 40 degrees from the base rim onto the boss on both sides. Stated drawing dimensions verified against the finished model geometry. Drawing notes: gusset apex height (~50.2 mm) follows from the 40-degree angle between rim (y=58) and boss wall (y=36); base neck modeled as the union of the R58 disc and a 56-wide stadium to the R28 lug end.",
