Snake Puzzle

This is a snake puzzle designed by mtairymd of Instructables. See his page for assembly instructions (and solution): https://www.instructables.com/id/Snake-Puzzle-3D-Print/ Approximately 4 feet of 3/16" bungie cord will be required (McMaster-Carr 8858T81 or equivalent).
I've included the gcode I used for my Ultimaker where it will print all of the required cubes for that color.
