How to Create a 3D printable Blender Model

Using Blender to create 3D printable models is easy, if you remember some stuff:

1. Make sure you do not have duplicate vertices: [editmode] W -> Delete Doubles
2. Always make sure, your objects are manifold: [editmode] [deselect all] Ctrl + Alt + Shift + W
3. Make sure all normals of your vertices are pointing outwards: [editmode] [select all] Ctrl + N
4. Export to STL and have fun!
