the work of the toy is shown here: https://youtube.com/shorts/3VJbX_yWjhs This mechanism was created on the basis of the well-known kinematics “Parallelogram of Chebyshev” Everything was printed with PETG plastic nozzle 0.4 layer 0.2 without supports. Except for the hand - it was printed with supports in layer 0.1. The assembly sequence of the mechanism should be clear from the screenshots. For assembly you will need: - 1pc mini gear motor GA12-N20 3v 30rpm.
