Its not a problem with your model i took a look and the printer power supply burned and the smell.is horrible hahahaI don't know what causing this, but it's not the model because I and other have printed this without problem. I think it may be a slicer problem, I would recommend that you put the part in the slicer again and make sure that all layers are in the layer preview, then make a new gcode file of that.
I find it okey to discuss problems here about printing my model, then i can get an overview if there is a problem with the model it self.
