When downloading the original file, it turned out that it was broken. I had issues with manifolds and I was not able to repair it.
So, I decided to rebuild the model in Freecad.

Here's the result.

Since I use Ideamaker as slicer, I split the model into two parts (top and body), because I wanted to print it bicolored. Ideamaker provides a "align selected models" mode, to support dual extrusion with my Raise3d printer.

The small body, I used to test the dual extrusion.

For printing I'd recommend to use a wipe wall.
Printing time was around 6.5 h
