Edit: It's not, the preview just showed the outcome of it being 3D printed, thanks Dape. :)

I don't think so. The download is in OBJ format. And Dape has posted one other thing before that was clearly not a spam. That thing was this robot.

But uh, Dape, this is not a 3D printer website.

Ok, that makes sense, I was wondering if Dape was trying to sell the funnel, as the example pic was in real life.

Dape,

I find your model interesting, thanks for sharing it!

If you search the 3D assets on this site, many could be adapted for 3D printing, or vice versa.
The only difference with this submission is the way it's presented, not the data.

This could be used quite easily in a 3D game. 

1. A tunnel in a game.
2. Sandworm entrance.
3 3D Mario-like game.
4. A prop in a laboratory.
5. Drain pipe for a building.
etc.

Sometimes 3D models serve as a great source of creative inspiration.
Keep the creative juices flowing!

Paul.
