[Greg Zumwalt], master of 3D-printed mechanisms, has published his Saber 2 project as well as an assembly Instructable telling you exactly how to put it together.
Saber 2 is a 3D-printed gear-and-cam saber-toothed tiger that can be motorized to show an excellent loping movement. It’s 14” long as well as 10” tall as well as consists of 108 elements of which 34 are unique parts, as well as everything moves with the assist of a 6 VDC 60 RPM gearmotor. With threaded PLA rods to keep everything together, as well as tapped holes to secure the rods, one imagines the printer would have to be quite finely tuned as well as leveled for the parts to move as elegantly as you see in the video.
Hackaday visitors may recall [Greg]’s 3D-printed jobs such as his balloon-powered engine as well as his toy car also powered by balloons.
