I know it has been awhile, but if you calibrate your extruder output, you will not have to putz with the extrusion multiplier. Plus, your model is quite under-extruded so you you may still be trying to find the right multiplier. Calibrate your extruder and then you can "fine tune" while printing. Also, make sure you have the nozzle diameter set to match the nozzle installed on your printer. Hope this helps if not too late.
