// Makes an open rectangular cuboid with X-shaped cross-bracing to reduce the need for material in 3d printing.
// The direction of the cross bracing can be aligned with the X, Y or Z axis. This module can be
// used as a drop-in replacement for {{cuboid()}} if you belatedly decide that your model would benefit from
// the sparse construction.
// the sparse construction. Note that for Z aligned bracing the max_bridge parameter contrains the gaps that are parallel
// to the Y axis, and the angle is measured relative to the X direction.
// Arguments:
// size = The size of sparse wall, a number or length 3 vector.
// dir = direction of holes through the cuboid, must be a vector parallel to the X, Y or Z axes, or one of "X", "Y" or "Z". Default: "Y"
