Loved the original snake file created by Zomboe. Thought I would modify the design slightly to make the snake bend both ways, by alternating the joiners between each fin 90 degrees.
I printed it on UP! Plus printer - 0.3mm, 10 degree support, fast speed. Took about 20 min.
Wiggly Snake V1 - flat joiners between the fins, alternating at 90 degrees.
Wiggly Snake V2 - a central axis at 1.6mm diameter. This may be more flexiable than V1 but BREAKS MORE EASILY!!
