Custom name keychain

This is a remix of the name keychain designs by @PurpleLakeWash and @MatthewGhost, focused on improving the inner word generation. I added a base layer to solve the common bridge issue, resulting in cleaner and more reliable prints. The code has been completely reworked and now includes new parameters such as circle placement (X, Y), inner word positioning (X, Y, and angle), and more for better customization. 💡 Printing tip: I recommend placing the upper face flat on the build plate so the imprint appears on top for a nicer finish.
