Mechanical flapping-wing mechanism—manual摆件 toy that mimics wing flapping through gears and a four-bar linkage

Maximum unfolded dimensions: approximately 353 × 93 × 130 mm

The non-printed components require 13 M2.5 × 10 screws and 4 M2 × 6 screws

Assembly instructions are as follows: the arrow indicates the screw insertion direction; the same applies hereafter

Please note the differences here

The shaft and crank are marked with a dot (front) and a bar (rear) to distinguish between front and rear and to determine position (the 12-sided shape allows theoretical adjustment of the flapping-wing posture)

Please pay attention again: the front and rear models have distinct markings for differentiation
