Step Mechanism 3D model

3D model of step mechanism with a cabin. The base of it is the simple step mechanism of Chebyshev. Without UV, animation and materials, just OBJ with some groups of polygons by supposed materials (chrome, steal, rubber, glass and other). Each part of model is a connected piece of geometry. (Export file from obj to fbx, stl, abc by Blender 2.8) Attention: If you want to print the model by 3D printer and connect an engine to make it walk - it doesn't work! There isn't a pair important beams that connect pairs of leg (you can add it yourself) and it has not any bearings. ** Attention 2**: the cabin and cabin's base are not brackets with mechanisms and can not be attached to mechanism in real.
