Yeah, after a lot of thinking and visualization and brain-storming, a lot of which was the sort of formless void of the wordless prayers of St. John of the Cross and what I would reach for in Buddhist meditation (but never managed to hold on to for long if I even reached it --- given that I was regularly hit with a bamboo can before being told to go sweep up in the bookbinding shop, probably not....) I've managed to make a bit of progress on a project to the point of an actual concept realized in 3D in my head --- the problem has been that getting from mental image to 3D model to files which will can actually be cut on a CNC has been nightmarish --- the 3D CAM tools which I can afford either won't use the tooling which I wish to use in the way I need to use it, or one which did converted a 1" x 1" x 2" test section into a ~140MB file after churning for ~18 minutes (I'll need for this to exist in multiples and to be as much as 48 inches long).

Since then, I've been working on a personal project to cut this, but I've been running into issues with the complexity of CSG objects.... tried using linear/rotate_extrude but they rotate the 2D tool representation as if it were being used w/ a 5-axis CNC, but most people (incl. me) use a 3-axis....
