A 6" twisting hexagon spire. You can print both parts individually, or merged. Don't scale it down too much or the gaps won't slide.
I printed my final prototype on a 4 yr old MK3 w/ .6 nozzle. It was printed as a merged print-in-place assembly, with a tri-color filament. I had to smack the bottom to get it moving, but it quickly smooths out.
I sliced it for you on a Prusa XL, but the parts will fit on a Prusa Mini.
