+==== Auto-fix holes ====
+  * To see if there are any holes in the mesh, go in Edit mode and go to ''Select > Select All by Trait > Non manifold''. This will select all vertexes on the edges of holes: \\ {{:3d_modeling:blender:remesh_non_manifold_edges.png?400|}}
+  * {{:3d_modeling:blender:remesh_settings.png?400|}}\\ Apply a remesh modifier to the object and tune the parameters until the object is defined properly:\\ {{:3d_modeling:blender:remesh_remeshed.png?400|}}
+  * Try selecting the non-manifold vertexes again. If there are still some selected, repeat the above process, or export the object to Meshmixer to remesh it there.
+The 3D print add-on for Blender is helpful in preparing your object for 3D printing: enable the add-on ''3D-Print Toolbox'' in the Blender preferences.
 ==== Delete unwanted geometry ====
 Cut away unwanted parts, like the surface the model was standing on.
