Google Sketchup (Pro Trial needed to import DXF)
1. Get what you want exactly in model viewer, including poses, etc
2. Export MQO files in from the model viewer
3. Open it in Metasequoia. OPTIONAL: If it has paper thin areas, copy/paste, extrude about 5 or so, and then invert the faces. That should thicken it up a bit.
4. Safe as a DXF file.
5. Open it in Sketchup Pro (there's a free trial)
6. Go to where all the points converge in the center, use the eraser tool to get rid of all of them. Make sure you don't accidentally erase any of the outside faces.
7. Use the
STL plugin for Google Sketchup to export to STL, the format that most 3D printing programs can use.
8. OPTIONAL: Use
Netfabb to clean up the STL to avoid any errors in 3D printing.
9. Print!
