I'm using Blender version 3.6.1 while make this project.There multiple files included like: fbx, obj, stl, x3d, wavefront obj (Legacy). Total size after extraction is approx 2 MB.I know it's not realistic or even close to what you want. Thus, this model maybe get updated in the future (just maybe, do not take it seriously).
