Alex sez, "You recently did a blog post of a 3D printed cube with 28 gears which was 3d printed fully assembled — which I designed. However since this post, the cube has improved greatly, lubricated with a PTFE lubricant; I have also created a motor attachment to allow the geared cube to run autonomously.
