  "description": "Modeled by an AI agent from practice drawing MPD131 by Studycadcam (blog.naver.com/studycadcam). A 100 x 45 x 13 mm base plate with a 19 mm-thick vertical wall on one end. The wall is 38 mm wide with a 38 mm straight portion topped by an R19 semicircle (total 57 mm above the base, 70 mm total height). A vertical 13 x 19 slot with R6.5 end caps passes through the wall centered on the wall's width, with its top touching the semicircle center. The base plate carries a Ø10 through-hole with a Ø20 counterbore on the top face, centered in Y and offset 45 mm from the far end. Stated dimensions (100, 45, 13, 19, R19, R6.5, Ø10, Ø20) are modeled and verified. Disclosed simplifications: the angled/triangular gusset visible in the iso between the wall's side and the base top is OMITTED — its taper and top-attachment point are not uniquely resolvable from the iso-only drawing. Counterbore depth (5 mm) is assumed, not dimensioned.",
