Hello. Here a short description, how I put all the parts together. In the model is space for a small atomizer-chip, wich produces smoke out of the chimney. It's called: 517C 5V Atomizer Board Driver USB. There is no soldering needed.

I recomend to use a very small amount of glue on the printing bed. I had some issues with the small parts getting lose on the bed. Some parts need to get printed several times. Look at the pictures for help.

I spraypainted all the parts first. To put the parts together I used super glue or everything glue. First you glue the input-part to the middle-part. Then you glue the chip inside, upside down with hot glue. Make shure the cabel plug is positioned behind the small hole on the front of the input-part. Then insert the plug with the atomizer at the other end and connect it with the chip. Then glue all the other parts together. The round atomizer is placed and glued under the chimney. Make sure the red cabel is facing up, or the smal metal area. Otherwise the defusing isn't working. Testing it, should also help.

There may be some parts, like the ladder wich dont fit into place. Just cut them into the right length. 

I'm happy to answer any questions.
