Cube loop fidget with bars

8 cubes in a loop, making a fidget that moves in a number of ways including turning on itself. The bars add a little tightness, making it more satisfying to turn but leaving enough looseness to roll along some fingers. This will often print with only critical supports. For the loosest, simplest version, try the basic cube loop. The best turning is the thick one, but it has very little space in the middle. The most impressive is cube in cube which is also a bit larger. If you want something that's difficult to turn, try the one with plates.
