I've made a couple of designs based on this idea before, but I realized that more segments = more fun, so now there's 35 😂 This design twists, expands, and collapses in a really neat way, and the segments can actually be separated and stacked as well! 

This model can be scaled up or down to preference, but be sure your build plate adhesion is good. Check out the gcode sample for the print settings I used. 

If you want to test this print with a smaller one first, there's a standard size model included. 

Happy printing!
