my english is not so good, im from germany xD
for short: when I save this File https://www.blendswap.com/blends/view/83856
as STL file with Blender, it looks like she is wearing some kind of glasses.
How can I prevent that to happen ?
In the left panel when you save there are an option unchecked, select it, "Selection only" and then export to STL, but before select only the mesh of rabbit.
