Do not reply to this, i have fixed it

Im printing this sword for a friend of mine, and Cura wont slice it, or it just takes a vary long time, its around 28 million tri's and has taken more than 1 hour to slice, its at the lowest resolution it can go, and has no supports. What can i do to try and improve it?

I am printing this object for a Fiero, and some pieces of the layers are missing. I have thin walls enabled and changing the line width makes it worse CE3E3V2_untitled.3mf
