Support free design competition
The Scissor Snake Support-free Product Design The "Scissor Snake" is a fun 3D printed toy. It is easy to print without support; the "Scissor Snake" comes off the build plate assembled and ready to use. Its motion is incredibly smooth, resulting in a very precise, fast, durable and fun remote grabber. The design uses an exclusive, support-less crossover bearing, engineered for this project. The engineered cross-over bearing further enhance strength and lifting ability by interlocking with the frame when fully extended under load, causing the frame to become rigid, thereby reducing stress on the bearing pivots. This results in a strong and durable toy cable of lifting many times its own weight. Kid tested. Guaranteed to provide many hours of fun for kids of all ages. Instructions Print at 100% scale, using 30% to 50% in-fil, no support, at 0.2mm layer height. The "Scissor Snake" is designed to print at 100% scale on wide range of 3D printers. However, if the print comes out looser than you'd like, you can reduce the scale by 5 to 10%; this will produce tighter joints. If the print come out too tight, increase the scale by 5 to 10%; this will produce looser joints. Normally this is not necessary. Otherwise, for best results, don't change the scale of the model. Volume: 51.5 cm^3 Print Time: 3:35 1.75 mm Filament Required: 15210 mm Inspiration Like most creative people, I collect my "really good" ideas in a notebook. Sadly, many ideas go into these notebooks and never come back out. This is the story of an idea that id made it back out of the notebook. When I learned of the "Support-free 3D Printing" contest, naturally I went to my "good idea" notebook to see what I might have hanging around. To make a long story short, I found some unfinished support-free bearing designs perfect for the contest. Stopping on the page shown in the inspiration image, the magic happened. As I sat there pondering the many possible applications of this bearing, I suppose this was the moment of inspiration when the "Scissor Snake" first came into existence.
