Heart with text box, I used Blender to add text to the heart and all 4 sides of the base.
Instructions text in Blender:
- Import both files into Blender
- Go to add
- Select Text
- Go to edit mode
- Type message (recommended to separate text by line)
- Tab out of edit mode
- Go to the A section of properties (bottom right)
- Extrude to the length you want (Geometry)
- Hit "S" to size text (pressing XYZ will size on selected plane)
- Position text on files (press "G")
- Export to STL
- Send to Slicer
