Speaker grille: an add-on for the left of the head
The Speaker grille add-on goes on the left of the head: a square of small round holes for a speaker behind it. It adds no plastic: it is cut into the head's shell. On a bot built by 3D3D it costs nothing extra, and it fits 1 of the 8 heads.

How it is priced
It sits on the left of the head. The price above is worked out on the Dome head on the Mini v2's body, from the same cost sheet as every bot: $0.11 a gram in PETG, so it is a few cents, not a new part to buy.
Finishing: none. No piece needs supports taken off and nothing is glued on, so it costs $0.00.
