There is a way to transfer the texture of any tree to a 3D printable object without harming the tree. It is possible to achieve this using just a mobile phone camera, photogrammetry software like Meshroom, and 3D design software like Blender3D for texture cleaning for further editing.

There are many trees that carry a piece of history or sentimental value for someone. It may be an oak, which can be hugged by five or more people. This tree outlived quite a few generations and maybe under protection of local conservationists. It could be a maple that holds a swing, or a pine with awesome cones. Even a birch 3D scanned texture can be transferred to an object. At the same time, the vase mode 3D printing is a brilliant time-saving technique for such tasks.
