The collection of 21 bits was made in Blender 4.4

Each model is in a separate file inside a folder with the corresponding format. 

All models are low-poly and consist only of triangles and quads. 

Each model has a non-overlapping UV map and a 2048x2048 png PBR texture. 

You can see the exact number of polygons and verts on the render of the corresponding model.
