Description

Roses are red.
Violets are blue.
My printer went brrrrrrr
So now this heart is for you.

This is a heart-shaped Valentine’s box that was literally 3D printed to contain my emotions (and also candy, jewelry, notes, or small chaotic objects).
The lid says it all:

“This heart was printed to hold my love for you.”

Because nothing says romance like layer adhesion and proper bed leveling.

🔥 FEATURES (UNHINGED EDITION):

  • Holds love, candy, jewelry, and unresolved filament issues
  • Lid fits tighter than my tolerance settings
  • Printed on a holographic build plate for RAINBOW HEART MODE 🌈💥
  • Bottom surface so shiny it reflects my commitment
  • Zero flowers harmed in the making of this gift

🖨️ PRINT SETTINGS OF LOVE:

  • PLA because commitment issues
  • Silk filament because ✨extra✨
  • Holographic plate because your love deserves DLC
  • Slow first layer because trust is earned

Give it to your Valentine and say:
“I didn’t buy this.
I printed this.
I watched it for 6 hours to make sure it didn’t fail.”

If they don’t appreciate it, increase wall count and try again ❤️
