Prompt that made this
Spur gear train. Five separate parts, not grouped: a base plate, and four meshed spur gears of 12, 18, 24 and 36 teeth, module 1.5, sitting in a row on the plate.

Why this one
Demonstration or teaching gear train that prints as five separate parts
Torque passes from gear to gear through the involute flanks of neighbouring gears. The centre distances equal the pitch radius sums, so the teeth mesh. The plate carries the gears.
