Description
This model is a romantic Valentine’s-themed keychain set for couples.
It consists of two separate heart halves, each printed as its own keychain.
When brought together, the two parts snap into a complete heart using embedded magnets, symbolizing connection and togetherness.
Each half includes a hidden magnet cavity, designed so the magnets are inserted during a print pause.
Once printing resumes, the magnets are fully enclosed inside the model, creating a clean, durable, and invisible magnetic connection.
Perfect for:
• Valentine’s Day gift
• Couple’s keychain set
•Anniversaries
• Meaningful, personalized 3D print
🧲 Magnet Information

Make sure magnet polarity is correct before resuming the print.
