The prompt
Design a plate-expanding cam mechanism, using the attached image as a reference picture, but change the model so it's able to fit through a cross-section circle with a radius of 1.6 inches when it's in the closed position. Then, make it so that in the expanded position, the outer legs reach a radius of 3.8. Keep the plated mechanism and the pin system. Adjust the plate sizing, leg sizing, shaft sizing, and plate guide line curvature as needed to fit that requirement. The only restriction on this is to make sure that, when fully compacted, it can fit through a 1.6 in radius hole and then expand to a 3.8 in radius hole
