Blend to Stl failing .

[fred_dot_u]

I've downloaded the model. Blender's 3D checker indicates 275 intersecting faces and I'm not so much a blender user that I can fix it within blender. When I load it to Meshmixer just to see the model, it contains too many triangles to load and crashes my computer, which is reasonably powerful.

I was able to load the file into Meshlab and used the filters to reduce the number of faces/triangles to 250,000, from a starting point of over two million. This allowed Meshmixer to load the model for analysis:

This picture shows zebra stripes, which represent reversed normals. These are faces which are "inside out" in that the surface is pointing inward. 3D printer slicers sometimes will tolerate such errors, but it's just bad form to have them. The blue and red markings are other error types.

Flipping it over in Meshmixer shows us that the wheels are zero-thickness surfaces, which of course, will not print.

I've attached the STL file with the mesh reduced, which would allow you to manipulate it more easily, but I don't have hope for this one.

It's one of those things that the creator manages to make free by not doing all the work necessary to turn it into a 3D printable model. He leaves the work up to the downloader. Either one becomes more proficient at Blender or the model doesn't get printed.

yes i understand now , that software you said also says that there is alot thin parts witch wont be printed . so i assume i have to give this up or spend some time learning blender thanks for help anyways
