Hey, I got a floppy cube (3x3x1) for some days ago. I played with it and then the center cap fell off. The one on the 3x3 side. I cant just click it on again, and there is a screw inside. I don't know if I should glue this on? Will it help? or will it make the screw stuck? I really don't know what to do. Please help! :fp
