Shopping cart stack 3d model rendered with Cycles in Blender, as per seen on attached images.

The model is scaled to real-life scale.

File formats:
-.blend, rendered with cycles, as seen in the images;
-.obj, with materials applied;
-.dae, with materials applied;
-.fbx, with material slots applied;
-.stl;

There are two sets of files, one with the stacks of trolleys, and one with single trolleys.
Files come named appropriately and split by file format.

3D Software:
The 3D model was originally created in Blender 2.8 and rendered with Cycles.

Materials and textures:
PBR material is being used, consisting of five 4k image textures (Base/Disp/Metallic/Normal/Roughness).

Certain 3d softwares can possibly need texture re-assigning in order to get the proper material effect.

Preview scenes:
The preview images are rendered in Blender using its built-in render engine 'Cycles'.
Note that the blend files come directly with the rendering scene included and the render command will generate the exact result as seen in previews.
Scene elements are on a different layer from the actual model for easier manipulation of objects.

General:
The models are built mostly out of quads and are subdivisable.
It comes in separate parts, named correctly for the sake of convenience.
