OpenSCAD listed on Thingiverse's Jumpstart

Customizer is running 2015.03 (latest) [ref]. So text() etc are available.

Ahem...Quoting Jumpstart "Every model that OpenSCAD exports will be a high quality, solid, watertight STL file that can be understood by 3D printer software like MakerBot Desktop or other model slicers. Unlike programs like Sculptris, OpenSCAD was written specifically to create 3D printable models, and therefore it never exports bad or broken geometry."...

Lol.. reminds me of the old saying "Never say never..."  As far as I
understand it, in theory the math model behind CGAL can guarantee "non
broken" geometry... (google for "regularized set operations", very rough
description is that it guarantees that if you start with two water-tight
objects, and perform an operation like union or difference, the result
will be a watertight object, which should propagate through the entire
object tree resulting in a water-tight overall model)

http://doc.cgal.org/latest/Nef_3/index.html#sectoinRegularized

But as I understand it, the theory gets a little messed up somewhere in
the thousands of lines of code in CGAL, OpenSCAD, binary floating point
conversion, re-conversion, ASCII decimal floating point conversion,
gcode, etc.

Re: In case you missed it

It works very well for me and I'm duly impressed. But you have to manage the Delta overlaps between volumes when performing any boolean op as adjacency is indeterminate.

IMHO this is where most people come unstuck making printable objects.

Another reason I love the # operator :) (and Wings3D :))
