Cube in cube loop fidget

12 cubes; 8 big ones in a loop and 4 smaller ones floating inside 4 of the big ones. All of the cube loops are impressive for people who aren't used to print-in-place but this is the fanciest that way. This turns well one-haded and will roll over some fingers. It's a relatively noisy fidget because the little cubes jingle.

Because this is large it does tend to need plenty of supports, but will still usually work with only critical ones.

For the loosest, simplest version, try the basic cube loop. For a version that is slightly less loose, making for a cleaner turn, but still has space in the middle try the one with bars. The best turning is the thick one, but it has very little space in the middle.  If you want something that's difficult to turn, try the one with plates.
