Chebyshev's foot walker

Video^: https://youtu.be/7CwmXkfgyzc

his toy is a model of Chebyshev's standing machine.

The model was printed with PETG nozzle 0.4 layer 0.2. All parts are printed without supports.

Need to print:
2x Big gear.stl
4x Big rod.stl
1x Body.stl
1x Bottom of battery covers.stl
4x Cam.stl
2x Connecting rod.stl
1x Cover.stl
1x CPU lock.stl
1x Engine lock.stl
2x Foot 1.stl
2x Foot 2.stl
1x Small gear.stl
4x Small rod.stl
1x Switch retainer.stl
1x Top of battery covers.stl
2x Axletree.stl

Body.stl requires post-printing: the supports need to be removed and the large holes need to be machined so that Cam.stl rotates in them without jamming. The assembly order is shown in the figures. Attention should be paid to the orientation of the bosses on the Big rod.stl - they should be oriented as shown in the figure. When assembling, the bolts should not be overtightened - all connections should be movable and move without effort.

The model can be assembled in two versions
