This might be off topic, but I still think it will fit in nice so I don't have to make a new topic.
How do you remove your center caps on your V-cube 5 and 7? I don't see how you do it.. On my V-cube 5 I take out the corner and the pieces around the corner and look at where the cap is, and as far as I can see it is fully attaches to the core piece, not being able to come off.. What do you do?
