Printed in the orientation as shown in the CAD model. The assembly instructions are easy to follow. All the fitment is very tight tolerances. It took me a while to push the various nuts into place because they were so tightly fitted. Use a needle nose pliers and take your time.
Once all together, it's very rugged. The hot end fits snugly into the holder. The dual fan was sort of necessity, as the blowers I have are 6V. Run in series it's doing fine except for some unresponsiveness in their operation at very low speed. The cooling fan on the hot end is also excellent with it's directed airflow.
So far using this for my 1.0mm volcano. Have a test print running and it seems to be great. If I were to print some metal, this would probably be worthy of it for the sake of durability.
