Here are cat ears for the Beats Studio 3 Headphone. The left and right ear are mirror copies of each other and don't vary too much so they can be used interchangeably without problems.
I printed these flat on the bed and came out fine. As long as the ears are inserted at the appropriate places, the clip shouldn't break. This may vary from printer to printer, however, so you may need to print this ear side on the print bed.
The infill percentage is what I trust my printer with. If the printer you're using has good overhang, you may not need any infill or less infill.
