The prompt
Generate a 3D CAD model of a 1D QRD N7 acoustic diffuser panel. Total block size is Width X=420mm, Height Y=800mm, Thickness Z=140mm. The block must have 7 linear parallel channels along the Y axis. Channel width is 57.4mm. Between each channel, add a vertical slot for dividers with a thickness of 3mm and a depth of 15mm. The depths of the 7 channels from the top surface are: Channel 1: 0mm, Channel 2: 23mm, Channel 3: 93mm, Channel 4: 46mm, Channel 5: 46mm, Channel 6: 93mm, Channel 7: 23mm. Export as a watertight STL file.
