Making an existing mesh manifold with Blender
121+
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
122+
123+
.. UPDATE: This relies on a specific Blender addon. If it becomes unsupported,
124+
.. we can remove this section.
125+
126+
If you have an existing mesh that is not already manifold, you can make it
127+
manifold using Blender.
128+
129+
In Blender, install and enable the
130+
`3D Print Toolbox <https://extensions.blender.org/add-ons/print3d-toolbox/>`_
131+
addon.
132+
133+
Select the mesh you want to make manifold. Open the sidebar by clicking on the arrow:
134+
135+
.. image:: img/csg_manifold_step_1.webp
136+
137+
In the **3D Print** tab, under **Clean Up**, click the **Make Manifold** button:
138+
139+
.. image:: img/csg_manifold_step_2.webp
140+
141+
The mesh should now be manifold, and can be used as a custom mesh.
