Needed a costume for halloween this year and couldn't find a good bender head online.
It all prints without supports and there is a little hole for a straw for drinking. The helmet does get quite warm, potentially a fan or cooling neck device would be good. The antenna affixes on top with a little hot glue. Just remember to scale both the same amount when printing. The one pictured was printed at 93% full size. Acrylic paint mixing a little yellow with white provided the color. The rest was printed in cool grey pla.

Mixing with a suit = fancy bender
