Hi everyone! I've acquired a 2x2x2 disassembled puzzle head. I've tried to assemble it and I'm stuck at the last piece. I have watched tutorials on how to assemble 2x2x2, and everyone says that it should be forced in at 45 degrees angle. I've tried that alot and it does'nt work... I'm afraid that it will break. If anyone has suggestions, please help! Thanks!
