Based on SMARTDAGGER's design: http://www.thingiverse.com/thing:817759
Scaled the helmet to 95% and sliced it into smaller pieces due to print size bed and to reduce support structure.
Glued together with cardboard as extra support and added foam padding from a bike helmet.
Painted with acrylic blue paint and white details is office paper with acrylic paint on top.
Buckle on strap is from: http://www.thingiverse.com/thing:1074129
Printet in ABS and I used a regular glue gun.
