This may be redundant because we all know what a 3x3 looks like on the inside, but I'm very interested in the Bump cube's internals. I heard it was made from a mini cube, but I can't imagine how that would work. Any brave soul want to open up their cube? You know you wanted to lube it anyways

The originals were made with Keychain cubes as cores. I have no clue what the core of the mass produced ones is. We'll all find out soon enough.

I disassembled my Mirror Blocks last night. The mirror blocks inside has almost all the measurements of a keychain 3x3, but the centers are as big as a normal 3x3. This is pretty weird. I always thought since the original bump cube it would have a normal sized 3x3 as a core... mister Takeji?

It turns better than a keychain cube, right?

Yes it's less 'clicky' than the keychain. Much more fluid. But it's not pre-lubed. Maybe this is due to the big centers.

Did you just pop an edge or are there screws?

Pop the edge. Don't take the thin ones and don't take the big ones. Medium sized are the best:P

here is a photo of the structure but it's not mine . I'm still waiting for mine

that looks like a normal sized core, but the screws arent as long as a normal cube.

The core does indeed look the same but the mechanism pieces are keychain-sized
