About this 3D model

String "Climbing" Christmas Tree is another string climber based on the dual spool design. It doesn't really climb the string, it just appears to do so. Consisting of 9 unique parts (11 total), and only requiring the purchase of embroidery floss, once assembled String Climbing Christmas Tree puts to use the "String Climbing Mechanism" and further illustrates how string climbing toys such as these, some over 100 years old, operate. Video of prototype is here: https://www.youtube.com/watch?v=n-LyBzluu74. "Bling" added by my wife. Designed using Sketchup Make 2016, sliced with Cura, and printed in PLA on an Ultimaker 2 Extended.
