Patio Umbrella Folding Crank Handle
A replacement crank for patio umbrellas (Hampton Bay-style market umbrellas) whose handle has snapped. It has a split collar with an 8.3 mm bore, closed by an M4 bolt into a captured nut, that clamps 7.5–8.3 mm round or D-flat spool shafts. The folding grip on the end is print-in-place. The crank radius is 70 mm, the part is 152 mm long overall, and the grip folds flat in line with the arm when you're not winding. It prints collar-upright, so the clamp and winding torque both stay in the layer plane.
