  "description": "Modeled by an AI agent from practice drawing MPD145 by Studycadcam (blog.naver.com/studycadcam). A crank lever: a 24 x 26 mm rectangular arm carries a Ø12 hole 25 mm from its left end, reaching across to a Ø42 hub 44 mm tall whose centre is 55 mm from the Ø12 hole (80 mm from the arm end). The hub has a Ø24 through-bore with a 6 mm keyway on the outer side, plus a 4 mm relief slot at the small hole. Stated dimensions 24, 26, 44, Ø42, Ø24, Ø12, 6, 4, 55, 80 are modeled and verified. Disclosed: the keyway depth past the bore and the exact relief-slot length are not dimensioned in the drawing and are taken as ~4 mm and ~16 mm respectively; the arm bar is extended to overlap the hub so they merge into one solid.",
