I really want to see one for a Mini QJ. Therefore the cube can easily be bought if need be and is quite affordable.
Do you have any links to its dimensions or pictures of the edges? I don't own one
Also, V2 should arrive in a few days. I plan on selling 4 edge sets and 8 edge sets. The reason is, I don't trust the edges being strong enough to be the last pieces popped in on a rubik's 4x4x4. If you really want a full set, you can allways order one 4 edge set and one 8 edge set.
