all normals got pointed to the outside.
But I am still not out of the woods - even though the normals are OK now. I attached a 3DM file baked from my current GH layout. The part is made using 4 basic steps: (1) capping the outside surface which is made by joining 2 surfaces, each lofted from 11 polyline curves, (2) capping the inside surface made by lofting 11 circles, (3) whacking 5 units of height off the bottom of (2) by doing SDiff with a 5 unit high capped cylinder, and (4) using SDiff to subtract (3) from (1)
Step 3 is necessary to allow for a solid bottom thickness of 5 units. All the surfaces are NURBS, none have been converted to meshes.
I would have thought that there would be no problems printing this part because it is made from only solid surfaces. The 3DM file has no naked edges - which is what I expected. But my generated STL file is 23.19 MB in size and the 3D Builder program says it has errors. The 3DB program "fixes" the errors, but when it does so it closes the top of the part, so that function is useless. 3DB will also simplify the STL file and create a resulting file that is much smaller, but this also has problems that would result in a failed 3D print.
I totally realize that my problem may lie completely outside GH & Rhino and I don't mean to add clutter up this board with extraneous posts. It's just that I have not had issues like this until I tried the idea of joining 2 lofted surfaces that have reverse twists. I have made many parts before that included reverse twists - but not lofted surfaces. Here is just one example: http://www.thingiverse.com/thing:1606442…

there is a gap there, so the pipes will not connect unless you make them larger and put rounded ends on them.
3. Most any 3D printer will have problems printing something as long and thin as your pipes are.
4. Attached is a screenshot of a section of you pipes (with flat ends to make them closed surfaces) after slicing with the Slic3r program. Except for that one outside corner, everything is connected. I'd suggest you try again with a layer height of 0.200 mm (or smaller) and a printer nozzle of 0.400 mm diameter (or smaller).
5. If you click on the Internalize option for the Crv component you will not need the Rhino file any longer - doing that loads the Rhino geometry into your GH file directly and saves it there.
6. Your pipes will need a lot of supports for 3D printing - but you already know that. Removing the support material from something that flimsy will be quite difficult. You would have better luck if you had a way to print them using a resin based printer - but these usually have smaller print volumes and are expensive.…

shift in U and V direction, setting the base and setting the size. It is kind of working. See the picture attached. The 3D object doesn't morph seamlessly yet. I think it has to do with the size of columns and rows of the grids.
I want to do this using grasshopper so I can set the parameters instead of hard numbers. I tried to use 3D morph in Grasshopper, however, I can only set the shifts in U and V directions, but I can not set the base or the size. I want my 3D object to span 2 units in U direction and 4 units in V direction, shift 2 units in U and 6 unit in V. The 3D object need to be able to tile seamlessly in 3D space.
Any information will be highly appreciated.

defined size from a list of available sizes.
4. The gap between gems is controlled.
5. Prongs are placed among gems and totally controlled.
Keep on working on algoithm to make it more universal, controlled and bugs free.
Thank you guys for showing me THE WAY! ^_^
Here is the subject to discuss. Maybe someone finds interesting turns in my logic.
