FDM-optimised wall shapes from BOSL2's ``walls.scad`` — parts that use less material and print
without support. :meth:`~bosl2.walls.Walls.sparse_wall` is an X-cross-braced open wall (and
:meth:`~bosl2.walls.Walls.sparse_cuboid` a solid-box variant braced along one axis);
:meth:`~bosl2.walls.Walls.corrugated_wall` a sinusoidal corrugated panel;
:meth:`~bosl2.walls.Walls.thinning_wall` and :meth:`~bosl2.walls.Walls.thinning_triangle` walls whose
middle thins away while the edges stay thick, joined by angled shoulders that don't overhang;
:meth:`~bosl2.walls.Walls.narrowing_strut` the home-plate strut those triangles are built from. The
honeycomb ``hex_panel`` is a follow-up.

Examples
--------

These mirror the examples in BOSL2's ``walls.scad``, rendered live through PythonSCAD.
Examples that rely on BOSL2's attachment/anchor system, or on features not in this port, are omitted.

.. rubric:: ``sparse_wall``

Typical shape:

.. pythonscad-example::

   Walls.sparse_wall(height=40, length=100, thick=3).show()

Thinner strut:

.. pythonscad-example::

   Walls.sparse_wall(height=40, length=100, thick=3, strut=2).show()

Larger maxang:

.. pythonscad-example::

   Walls.sparse_wall(height=40, length=100, thick=3, strut=2, maxang=45).show()

Longer max_bridge:

.. pythonscad-example::

   Walls.sparse_wall(height=40, length=100, thick=3, strut=2, maxang=45, max_bridge=30).show()

.. rubric:: ``sparse_cuboid``

A cross-braced box, braced along X:

.. pythonscad-example::

   Walls.sparse_cuboid([10, 20, 30], dir="X", strut=1).show()

Braced along Y:

.. pythonscad-example::

   Walls.sparse_cuboid([10, 20, 30], dir="Y", strut=1).show()

Braced along Z:

.. pythonscad-example::

   Walls.sparse_cuboid([10, 20, 30], dir="Z", strut=1).show()

.. rubric:: ``corrugated_wall``

Typical shape:

.. pythonscad-example::

   Walls.corrugated_wall(height=50, length=100).show()

Wider strut border:

.. pythonscad-example::

   Walls.corrugated_wall(height=50, length=100, strut=8).show()

Thicker corrugation:

.. pythonscad-example::

   Walls.corrugated_wall(height=50, length=100, strut=8, wall=3).show()

.. rubric:: ``thinning_wall``

Typical shape:

.. pythonscad-example::

   Walls.thinning_wall(height=50, length=80, thick=4).show()

Trapezoidal:

.. pythonscad-example::

   Walls.thinning_wall(height=50, l=[80, 50], thick=4).show()

.. rubric:: ``thinning_triangle``

Centered:

.. pythonscad-example::

   Walls.thinning_triangle(height=50, length=80, thick=4, angle=30, strut=5, wall=2, center=True).show()

Resting on the ground plane:

.. pythonscad-example::

   Walls.thinning_triangle(height=50, length=80, thick=4, angle=30, strut=5, wall=2, center=False).show()

Only the diagonal edge thickened:

.. pythonscad-example::

   Walls.thinning_triangle(height=50, length=80, thick=4, angle=30, strut=5, wall=2, diagonly=True, center=False).show()

.. rubric:: ``narrowing_strut``

A support-free strut:

.. pythonscad-example::

   Walls.narrowing_strut(w=10, length=100, wall=5, angle=30).show()
