After printing the support should snap of easy by twisting it and the snake is fully functional. There will be a little support left in the ball joints but this will fall out by playing with it.

The file includes support that should work on more systems than my own. I print most of my stuff with these settings:
Layer height of 0.15 mm (If you want a really clean object, use less).
Outer walls speed 60 mm/s, infill 75 mm/s. Infill 25%,
bottom and top at 0.6 mm and walls of 0.5 mm thick.
I advise to use a brim to keep the 23 parts on the build platform until they connect.

It's a 51 cm (20 inch) friendly snake that doesn't bite or strangle, and it's free! I do appreciate feedback if you print it ;o)
