Chain Reaction aka Space Cubes

Six identical parts, easy to print, not so easy to assemble :)
I saw this on utube the other day and thought it'd take 5 minutes to copy, especially thanks to the photo on the spacecubes.ch website...
It did take me 5 minutes to model, but turns out it's very NOT forgiving in terms of tolerances. I wanted it perfect - loose enough while assembling that it's hard and two brackets can't be grabbed by a third, but still rigid enough once assembled. Took me six prints in various sizes, but I got it. Enjoy!
