// Module: sp_neck()
// Usage:
// sp_neck(diam, type, wall|id=, [style=], [bead=]) [ATTACHMENTS];
// Description:
// Make a SPI (Society of Plastics Industry) threaded bottle neck. You must
// supply the nominal outer diameter of the threads and the thread type, one of
// 400, 410 and 415. The 400 type neck has 360 degrees of thread, the 410
// neck has 540 degrees of thread, and the 415 neck has 720 degrees of thread.
// You can also choose between the L style thread, which is symmetric and
// the M style thread, which is an asymmetric buttress thread. You can
// specify the wall thickness (measured from the base of the threads) or
// the inner diameter, and you can specify an optional bead at the base of the threads.
// Arguments:
// diam = nominal outer diameter of threads
// type = thread type, one of 400, 410 and 415
// wall = wall thickness
// ---
// id = inner diameter
// style = Either "L" or "M" to specify the thread style. Default: "L"
// bead = if true apply a bad to the neck. Default: false
// anchor = Translate so anchor point is at origin (0,0,0). See [anchor](attachments.scad#subsection-anchor). Default: `CENTER`
// spin = Rotate this many degrees around the Z axis after anchor. See [spin](attachments.scad#subsection-spin). Default: `0`
// orient = Vector to rotate top towards, after spin. See [orient](attachments.scad#subsection-orient). Default: `UP`
// Examples:
// sp_neck(48,400,2);
// sp_neck(48,400,2,bead=true);
// sp_neck(22,410,2);
// sp_neck(22,410,2,bead=true);
// sp_neck(28,415,id=20,style="M");
// sp_neck(13,415,wall=1,style="M",bead=true);
// Thread specs from https://www.isbt.com/threadspecs-downloads.asp
// T = peak to peak diameter (outer diameter)
// I = Inner diameter
// S = space above top thread
