|

This cosplay consists of 3 components:
|
||||
|
||||
## Trident
|
||||
|
||||
The trident is composed of individual segments, made of acrylic, and a 3D
|
||||
printed head (convention rule prohibits metal) with a metallic paint. To ease
|
||||
transportation, the trident handle has individual segments with threads and can
|
||||
be assembled on site.
|
||||
|
||||
## Snake
|
||||
|
||||
A 3D printed snake with a soft material so it can wrap around and bend
|
||||
|
||||
## Wings
|
||||
|
||||
This is the crux of the cosplay and the most complex component. The wings mount
|
||||
on a wearable harness. Each wing consists of 4 segments with 3 joints. Parts of
|
||||
the wing which demands transluscency are created from 1/16" acrylic panels.
|
||||
These panels serve double duty as the exoskeleton.
|
||||
|
||||
The wings are labeled r1,r2,r3,l1,l2,l3. The segments of the wings are labeled
|
||||
from root to tip s0 (root),
|
||||
s1, s2, s3. The joints are named (from root to tip)
|
||||
shoulder, elbow, wrist in analogy with human anatomy.
