Hello, nice you're printing it. I hope you like it when it comes out.
As for supports, I've seen other spiral things here on Thingiverse and they don't seem to need support, rather just let the print 'climb up'. I was hoping this design would do the same, but that hasn't worked out, maybe the angle wasn't steep enough. I've used Cura as well, and I got a cylindrial support structure as well.
