Magic hand spinner cube

Description

There's no assembly required for this anti-stress cube. With the .3mf file you'll find my settings, I fill the cube to 50 % and occasionally add supports to ensure print quality. You can activate or deactivate the smoothing of the upper parts. 

For better cube rotation, you can add a few drops of lubricant to limit friction.
 

Assembly

None! This is print-in-place :-)
