I can't export my object as an .stl. I started with a UV Sphere and I used a boolean modifier on it and joined other objects to it. I removed doubles, re-calculated normals, tried triangulation, selected the object when exporting. Nothing works and the .stl file is empty. I also uploaded it to https://netfabb.azurewebsites.net/ and it was rejected. Any suggestions?
The Local View is enabled for this object in your file.
Local view isolates the selected object or objects, so that they are the only ones visible in the viewport.
Press NumpadSlash to exit it, select the object and try exporting again.
A side note:
- although you recalculated normals some of them are still inverted (the bottom);
- the topology of the mesh is a bit off, especially on the bottom, which can cause unexpected results when triangulated.
- scale of the mesh isn't applied (which can also be undesired);
However, this doesn't affect your current problem directly.
Try this: Create a new default start-up Blender file. Append your sphere from your original file into this new Blender file. When it is appended (so you can see it in your new Blender scene), select it and export it as an stl. Does that work for you? It did for me... this is what I get:

Let me know...
