I just got my Aolong v2, but immediately after, I lost the spring. My dad told me he wouldn't buy me another cube because my other ones broke and he said I needed to be more careful. I took the springs out of some ballpoint pens, but they were too big (although they were perfect in tension). Since the spring is perfect in everything but size, I feel like I need to cut it. Can someone give me suggestions for what to do?
