String "Climbing" Mechanism

myminifactory

String Climbing Mechanism is a cleverly designed dual spool string mechanism found in many vintage toys that still fascinate kids today. Although it doesn't literally climb strings, the ingenious design creates an illusion of movement with its spinning parts. This classic mechanism consists of only six distinct components and requires just embroidery floss and glue to assemble. Once put together, String Climbing Mechanism showcases how old-fashioned toys work their magic. I've successfully incorporated this mechanism into a few innovative toy designs that are sure to delight both kids and adults alike. You can check out my prototype in action on YouTube at https://www.youtube.com/watch?v=INctzet3oAo. For those interested in exploring more string climbing toys, I've also shared a video featuring various models at https://www.youtube.com/watch?v=Z92M0Gh4rGo. I designed String Climbing Mechanism using Sketchup Make 2016 and brought it to life with my Ultimaker 2 Extended 3D printer, which used PLA filament for the prints.
