Yikes ... a quadruple screw blank... That looks to be just a tad bit complicated and VERY expensive. It may be less expensive to try to do that with inlay (blue and red on white background). I saw a video online explaining how to do a 2-part screw blank design, where 2 spirals get wound round each other and then they get glued in place by acrylic casting ... he also did several with just one screw suspended round the barrel tube, so that the clear acrylic was transparent around the wooden screw. The cutter was kinda tricky to manage, as I recall. By changing the angle of reference, you could incorporate more than 2 spirals of varying thicknesses and possibly create a design just like that ... it may be that the same person who made that video happened to make that blank. In fact, he teaches a class and makes pens out of acrylic cast lego pen blanks and worthless wood cast blanks all the time. I don't recall where, but if you can contact him it might net you a few blanks like what you're looking for. edit- Video Link:
