Digital Talisman - Enhanced Keychain Version

After completing the original version, I realized that the ring part was too thin.If it's attached to a bag while going out, it might break and fall off.I added a reinforced keychain ring at the bottom and cap, providing a double ring for extra security.I removed the horizontal fixation at the original ring position and slightly enlarged the hole, making it easier to change the middle tag according to mood or need.Additionally, I added a rim around the middle tag to ensure it stays securely in place and doesn't fall out.原版的印完之後發現吊環部分太細了，如果是掛在包包上外出可能導致斷裂脫落。我在底跟蓋子部分新增了強化版的鑰匙圈吊環部分，雙重吊環更安心。捨棄了原本吊環位置的橫向固定，並稍微放大了孔洞，方便依照心情或需求更換中間的字牌。中間的字牌部分新增一圈方便靠在中間孔洞也不會脫落。
