Removeable Mesh Shelf or Basket

Our van build has some difficult to use space in the closet. I made these shelves / baskets to use that space.

There is a top "Bracket" that the lip of the basket slides under, then it sits on a "cleat" below.

The OpenSCAD and rendered STL (huge) are enclosed in the attached 7-Zip file.

For quicker rendering and a smaller STL, make $fs and ang_incr large:

$fs=0.5;
ang_incr=1.0;

For smoother curves (and huge STL) , make $fs and ang_incr smaller:

$fs=0.1;
ang_incr=0.25;

This may make rendering take ~ 24 hours.

I have a super inefficient way to generate the spiral curves used to wrap the mesh around the curve of the basket. The obvious solution is to use a spring library, but for very steep springs, the "wire" becomes oval shaped since it is extruded in X-Y and not along the path of the "wire". As a "quick" fix I create a series of spheres that follow along the path. Works great but makes a hugely complex STL.
