Infinity Cube with balls inside

The special thing about this Fidget-Cube in comparison to similar constructions is:there are balls inside the cubes (please do not ask for the deeper meaning, it's a toy)the cubes can be printed individually, in different colors and different materialsthe cube can be disassembled and repaired, if there were broken hingesThe balls have to be printed first, and then inserted into the cubes during a color change at height of about 16 mm (you do not realy have to change the color, but stop the print in some way).The individual cubes must be assembled after printing, and the hinges fitting tight and need sometimes a lot of force to put them into place.In return, you get a colorful toy that is a real hand cuddler due to its rounded edges and corners, and that can also survive or be repaired in a rough fall. Print instructionsFirst you have to print 8 Balls, and assemble them. Then you have to print 4 cubes, 4 mirrored cubes and 8 hinges.I like to print the hinges with PETG, because it is
