Cleanup for 3d printing

The 3d objects from the structure 3D scanner need a bit of work before they are printable.

The structure scanner delivers the 3d object in several parts. Let's bring these chunks together to a single object

select all go to 'mesh > cleanup > merge by distance' The amount of vertices that have been removed appear on the bottom of the screen.

There might still be some unintended clumps from the 3d scan floating around. Let's delete them.

• alt + a deselect all vertices
• select one vertex on the mesh that you want to keep
• l select linked vertices
• ctrl + i inverse the selection
• x delete the selected vertices
