(I know it's supposed to be Smilodon, but I needed the pun!)
My first articulated design done all in TinkerCAD, this model came as a personal challenge to make a robot toy in the program. After a few iterations, I was able to get this model to the point I wanted it to be.
Easy print, print flat with no supports. Scales well as I put a lot of tolerance into the joints.
