That works in Slic3r - but not perfectly. I'd like to be able to set 4 or 5 solid top shells.
This seems like it would be fairly easy to do in Sketchup. Import the STL, (You'll need a plugin for that), and clean up any loose junk hanging from underneath. Drop a line from each corner to a common rectangle beneath, forming your base plate. Then use Solid inspector (another plugin) to find any extra/missing geometry. Export to an STL, and boom.
Yup, that was my first thought and seems the simplest. But I've tried that, Sketchup just locks up when the .stl is imported :(
Marm, that sounds pretty easy...
I've installed SketchUp and the stl plugin:

I don't have an option to import an stl:

What am I missing?
Nothing, you need to use 'Import' not Open to read the .stil but I've tried on two machines including a powerful MacPro and SketchUp just hangs. Suspect the importer can't cope.
That is the window from the Import menu item. Perhaps my plugin isn't plugged in properly?
Possibly, I'm on a Mac and it's available as an option here. I auto installed mine from the Extension Warehouse.
sketchup sucks.
Can't see it working - but you never know.
But I would like to know why s3d doesn't add any support to a floating model. That can't be right.
