Smooth turning, not much of a challenge compared to its Version B and C. However, it's fairly easy to swap pieces between those cubes, and as a result I made with this cube a center-less cube. The result was much much better than holly cubes because it benefits from the rotation of a normal cube while not having those center pieces. I wish a version D would exist like this.

Not much corner cutting and turns pretty sandy, but a interesting challenge and I recommend.

Nice and smooth turning, the missing 3x3x3 mod?. Something different! I like it. J2018
