Here is a video explaining the cube...https://www.youtube.com/watch?v=Bc7L6P6V9fE&feature=youtu.beThis is a cube the I reverse engineered and designed... it will print with a single extruder or a dual for full color like you see above...You will need to print 1 cube core, 6 cube spinner arms, 8 corners, and 12 middle pieces to get a full cubeWill print in .1,.2,.3mm layer height....No need for supports on middle pieces if orientated correctly...Do not print spinner arm with supports....Corner pieces need supports, so does the core...
