This is the model of an articulated, modular snake.
Print the head and tail once, and as many snake segments as you like. Just attach them to each other after printing.
If the connection is too tight, use a rubber mallet, if it is too loose, use some glue or double sided tape. I've tried to get a good connection printing on a Prusa MK4 or Bambulab X1C with standard settings.
Also, since each module is printed separately, you can create stunning multi color snakes without having a MMU or AMS system!
A 20cm version with head and tail can be printed on a Prusa MK4 (without input shaper) in about 4 hours, with input shaper in 3,5 hours and on the X1C also in about 3,5 hours.
Our 2m long version took round about 24 hours combined to print (printed on mk4, x1c and mk3s).
Here is a video about the snake and how to create your own articulated (flexi) animal in a few minutes (in german):
The author marked this model as their own original creation.
