Let's see if I got this straight.. So, I need to transform the inkskape path
to points, then apply a function to map the points vertically..?

That would not be such a big problem. I will cut the object in half, so that
the maximal distance from the plate won't be that big. Then, I will apply a
support which looks like a mesh, easy to clean. Or, I will simply print it
vertially. The traversal bars are not that important, they can be glued
afterwards.

If you are referring to my code, the answer is yes. But you will need an
additional processing of inkscape path. In my code, the sweep paths are the
center line of the frame and bars. They should be computed from the inkscape
points in some way.

The modulation function I used may be changed to whatever you need. But
don't expect good results with big grid warping.

There is another detail. I have not used the sweep versions I have
referenced as is. You may try to use just the minimum torsion sweep I
submitted to the forum. The original sweep will do a horrible mess in the
frame corners and Oskar's minimum torsion sweep doesn't work well at the end
of closed paths.

I am working now in a more general sweeping method that will allow a better
control of the sweep torsion along the path. I don't believe I will be able
to conclude this version until the middle of the next week. My weekends are
rather busy :)

You may experience a certain instability printing it vertically. If you try
it, set a good raft.

You should check what your distribution provides. For most bigger
distributions there's a maintainer taking care of an OpenSCAD build
that works well for this distribution.

There's still no simple way for building a generic version that
will just download and run without any issues. Maybe Xdg-App or
a similar project will solve that in the future.

ciao,

Well... I am using version 2015.03-2. I don't know if my code will run with
version 2014.03. Sorry.

I’ve been running a 3D Printing operation for at least the last 6 years.  Once we moved to soluble support machines (we currently have 3), I started to view anything less as a toy.  There’s just so much more you can do when you don’t have to spend all your time dealing with support issues (designing it, removing it, etc.)  Most of the things we print simply could not be done without it.

@Kenneth: What dual extruder/soluble support tech would you recommend as
simple and reliable? Ie, which brand of printer have you had the most
success with, and what combination of model filament/support filament works
well?
