Prints in 30 min or less. Fits on 150x150mm print bed. For extra fast printing: Print at .3mm layer height with no supports. There are two tail types pick whichever one you like more. I like tail 1 the most.

Also:

If you would like to make a snake any size you want there are files for a connectable version too. 

The connectors come in different sizes. The thickest being the strongest but least flexible. The thinnest being the most flexible but weaker.
