💡 Printing tips for a sublime result

📌 Recommended filament :

• PLA : For a rigid structure and crisp details (ideal for invitations or "frame" envelopes). Suggested colors : Cherry red, powder pink, pearly white, rose gold.
• TPU : For a soft and flexible envelope (perfect for love letters to be handled with tenderness). Suggested colors : Pale pink, mauve, mint green.

📌 Print support :

• Use pale pink or transparent tulle for a "floating leaves" effect around the design.
• A pause after the first layer is planned to install the tulle with magnets (delicate and romantic effect guaranteed !).

📌 Print bed :

• A print bed with small stars adds a magical and celestial touch.

📌 Settings :

• Print at a slow speed (40-50 mm/s) to preserve the intricacy of the interlacing.
• For a metallic effect, use a special filament or add a touch of gold/silver paint after printing.

💬 A word about this creation…

I was deeply inspired by the beauty of the bonds that unite hearts – these invisible yet so powerful connections. If you have suggestions for other romantic designs (geometric hearts, constellation patterns, etc.), I'm all ears ! Your feedback will help me create even more touching and personalized envelopes.

PS : For an even more personal touch, you can add a small lipstick print on the corner of the envelope… or slip a sprig of dried lavender inside ! 🌸
