The prompt
I need to design a replacement knob for an oven. The top (front face) of the knob is 31.4mm in diameter, the base of the knob is 34.7mm in diameter. The knob is 22mm tall, with a very small rounded edge on the top. The walls of the knob are 2mm thick. There is a central shaft of the knob where it connects to the stove. The shaft is 12.6mm in diameter. It has a D channel in the central shaft. The shaft has a 1.9mm wall around the curved part of the D, and a 4.6mm wall at the center of the D to the outside of the shaft. There is an indicator line etched into the outside of the knob 1mm thick, 0.5mm deep, it is centered on the knob, parallel to the flat side of the D. when viewing from the bottom, with the D shape in proper orientation for the letter D, the indicator points down. The indicator extends 7mm across the top, and 11.5mm down the side.
