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
|
2024-06-25 06:11:48 -07:00
|
|
|
from root to tip s0 (root),
|
|
|
|
s1, s2, s3. The joints are named (from root to tip)
|
2024-06-24 16:13:15 -07:00
|
|
|
shoulder, elbow, wrist in analogy with human anatomy.
