This comb actually works and makes the "comb noise" when the tines are plucked (?) in sequence.

Print at 1 shell and 100% infill to make tines without holes.

Print it with 1 shell and 100% infill at a thin layer height for the best results.

If you go with a more coarse layer height, you'll need to use the bottom of the print as the leading edge of the comb in practice, because the plastic spurs will likely catch hair.
