Standard spinner rings are rather easy to build because they are based on simple ball bearing.
The problem with your design that you want working, spinning 3D, 2 piece Helix pattern - it will be very hard to construct.
I am really curious if someone here will offer you serious project for a piece so complicated.
The idea is "DNA helix spinner ring". If you have another idea (e.g. a different DNA design) then you're more than welcome to pitch it!
