Halo ring: an add-on for the top of the head
The Halo ring add-on goes on the top of the head: a thin ring that sits on the top like a halo or a light ring. It adds 0.7 g of PETG and makes the bot 2 mm taller. On a bot built by 3D3D it adds $0.07, and it fits 6 of the 8 heads, the Gem head included.

How it is priced
It sits on the top of the head and makes the bot 2 mm taller. The price above is worked out on the Gem head on the Mini v2's body, from the same cost sheet as every bot: $0.11 a gram in PETG, 1 extra piece, so it is a few cents, not a new part to buy.
Finishing: 1 kit piece to glue on. 3D3D charges $25.00 an hour for that, counted by the minute when it slices the job, so it is not in the figure above.
