Round vents: an add-on for the top of the head

The Round vents add-on goes on the top of the head: seven round holes in a flower pattern. 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 4 of the 8 heads.

How it is priced

It sits on the top of the head. The price above is worked out on the Mini 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.
