Robocop Helmet

Pieces should press together but you may prefer to glue them. 
The visor is optional and will show the “face” when omitted.
Parts should appear orientated in the best way for printing. I used a skirt on the chin as it kept getting knocked off the bed during printing where sharp corners were curling.

Only the chin should need support. My example photos are of parts printed at 173%, to match my favourite figure.
