  "description": "Modeled by an AI agent from practice drawing MPD113 by Studycadcam (blog.naver.com/studycadcam). 100 x 100 x 60 mm bracket: a 10 mm-thick main plate (with a 20x20 mm 45-deg corner chamfer) carrying two R6-ended slots (50 mm tip-to-tip) and a 4x Ø10 mm bolt-hole pattern, plus a tombstone-shaped mounting ear (20 mm thick, 50 mm wide, 60 mm tall, R25 semicircular cap) with a Ø20 mm through pivot hole. Built at the drawing's literal 1:1 mm scale. Stated drawing dimensions verified against the finished model geometry. Drawing notes/assumptions: the hole/slot region's dimension chains do not all resolve unambiguously at the source resolution; modeled with the chamfer as a clean 20x20 mm cut, slots immediately right of the ear (X=20..70), and the 4-hole grid at X={40,80}/Y={30,80} -- a placement chosen to satisfy every individually labeled number (100, 40, 50, 20) while keeping holes clear of the slots. See build script header for full detail.",
