Kaleidocycle of Möbius (updated hinges)

thingiverse

I downloaded a Kaleidocycle design from Vitroid's profile on Thingiverse, but unfortunately, it broke easily when I tried to assemble it. So, I decided to go back to basics and create the basic shape in SCAD, then redesign the hinges to make them more sturdy. To add some extra stability, I used 25mm diameter x 2mm thick metal bars as the rolling points.
