Fusion360 was too complicated, so I had to use PrusaSlicer's modifiers for the screw holes. Modifiers only export with .3mf, so just drag and drop the .3mf into PrusaSlicer. I'm not sure if this works with other slicers. Set infill to 0%.
Or just use the gcode
The author remixed this model.
I added new screw holes and scaled it down a bit to fit onto the 40mm fan and the 25 to 40mm fan shroud.
