The prompt
Generate a 3D parametric solid model of a speed loader main frame. Start with a central hub of 25mm outer diameter, 10mm thickness, and a 10mm center bore. Create 6 cylindrical cavities arranged radially at 60-degree intervals. Each cavity has a 41.10mm inner diameter, 50mm depth, and its center is 55mm from the hub center. Connect the hub to each cavity with a straight arm. Each arm has a 5mm width and 8mm height. Exactly 15mm before the distal end of each arm, reduce the material thickness to 1.5mm to create a living hinge. At the very end of each arm, add a retention tip with a 2.0mm hook height, a 15-degree release chamfer, and a 23.5mm inner radius matching the cavity. Add a simple hinge mounting point on the rear face of the central hub."
