Parametric True-Weave Rectangular Basket

Parametric True-Weave Rectangular Basket This is a fully parametric, support-free rectangular basket generator built in OpenSCAD. While many 3D printable baskets rely on simple boolean intersections or surface bump maps, this model uses piecewise trigonometric functions to generate a true alternating weave. The Weave Mechanics The horizontal bands don't just intersect the vertical ribs; they mathematically weave around them. The wave function is phase-locked to the dynamic rib positions: Corner Wrapping: The algorithm calculates perimeter arc-lengths and forces an outer phase reset at every corner. The bands will always wrap proudly around the outside of the corners, exactly like real rattan or wicker. Over-Under Alternation: On the flat spans, the weave flawlessly alternates inner/outer across the ribs, flipping polarity on each consecutive Z-layer. Dynamic Tapering: As you adjust the base versus top dimensions to create a draft angle (taper), the ribs automatically remap their spacin
