The prompt
Design a parametric egg roller tray for an incubator. It consists of a rectangular outer frame with dimensions 300mm by 200mm. Inside the frame, place 6 parallel cylindrical rollers, each with a diameter of 20mm, spaced evenly to hold chicken eggs. Add a small gear connection at one end of the rollers for motor coupling.”
