Update it was brought to my attention. That some people are having issues with this printing. It somehow defaulted in the support settings. You need to use tree hybrid. Support. If you are having trouble with the print. 

 Print the tornado and   2 bearing holders. Place a #608 bearing in each holder. They fit snug. Then glue one to each end. Of the tornado shaft.

use a 

 M8. Or 5/16th Threaded Rod about 24 Inch . 

 3 Nuts. 

glue. 

thread  2 of the nuts onto the threaded rod. Slide the completed Tornado Assembly Over the rod. Add the last nut. Position it so there is about an 2 "  or 50 mm of rod Sticking out of the top. Then tighten everything down. 

You will need to download taz separately. He was not my model to share. You want to print the model as is. But you do not need his feet. You will however need to add. A hole between his legs. For the rod. Either use your slicer And add a negative part. Or drill it out after print.  

 Add a little glue to Taz's legs. (stumps) And glue him into the Smoke Ring.

After the glue sets. Place him on top. Like a Christmas tree *. I put a little hot glue inside mine so that he stayed snug. And did not spin.
