It is exceptionally loud, but it's probably more due to the texture of the cubies not being perfectly smooth. the insides do still have some print lines, though they aren't big enough to impact performance to a severe degree. I still imagine the cube would be much better off without them, though.The slice moves seem a bit awkward in the video. Just me?
Also that cube is loud, or is it just the recording?
It's also PLA, so slices were a little awkward. they flow better with softer plastic, which PLA is really not soft at all.
My slice turns are also awkward because of turning style, so eh XD Not much that I can say. they weren't too bad though.
I also did a spring swap from MGC to YAN 3 springs after the video, which seemed to help fluidity.
