Sci-fi based clone tube model. Design is my own.

Hard-surface subdivision surface topology.

Complete modifier stack hasn't been applied to easily make modifications.

The empty at the center is an essential part of the modifier stack, so please only delete it after applying the array modifier.

For transformations select both empty an the clone tube.

Both subsurf modifiers use 0 levels for viewing, but 2 levels for rendering.

Included in the blend file is a simple backdrop to test glass material setup.
