Based on an original character idea, the Elbrandir's Helm is a wearable helmet complete with rotating backplates. The pieces are separated for ease of printing and adjusting.
I printed mine with ABS plastic, and created an ABS Slurry solution with leftover plastic dissolved in acetone to glue the parts in place. I chose not to put in extra motors because I installed an LED visor, but this helmet allows users great flexibility for flexibility in movement.
However, there are no predefined seams or reference nodes for screwing or gluing the parts in place. This is because this was designed to be able to have more moving parts, if motors were added.
