I wonder if anyone can advise me on a workaround here. A friend has asked me if I can print this .stl that is a scan of a sea bottom wreck site. Very cool but the .stl is is a tricky one as the seabed is so irregular. I'd hoped that I could setup Simplify3D with 100% support so the gaps between the 'seabed' and the print bed were filled but it doesn't seem to work. The end result is a very scrappy looking print with parts of the seabed resting on strands of support.

I tried to open it in Sketchup but the app hangs. Is there anything I can do to help here?
