Create high-quality custom trays for gifts, organization, or home decor. This project was developed to offer maximum flexibility: simply adjust the dimensions, and the script seamlessly recalculates the heart border distribution, maintaining a flawless geometry designed for support-free 3D printing. Perfect for both personal use and the production of unique, exclusive pieces.

CUSTOMIZATION
---

The model is designed so that any user can configure it quickly, with the number of hearts being automatically calculated to fill the entire perimeter!

1. Basic Settings
- Tray Length & Width: Maximum exterior dimensions of the tray (mm).
- Base Thickness: Thickness of the base along the Z-axis.
- Cut Inner Hearts: Enables boolean subtraction to remove the inner portion of the hearts, yielding a smooth interior wall.
- Alternating Layers: Enables horizontal offset (half-step) on even layers, aligning geometry in a brick pattern.
- Number of Layers: Quantity of heart rings stacked along the Z-axis.
- Heart Base Size: Size of the heart (mm). The script recalculates the perimeter and automatically adjusts the instance count.

2. Engraving & Text Settings
- Enable Top Text: Adds embossed (raised) text to the center of the base's top face.
- Enable Bottom Logo: Adds debossed (engraved) text to the base's bottom face.
 

3. Advanced Settings
For users who want fine-grained control over mesh and placement:
- Heart Width / Thickness / Height Ratio: Individual scale of the heart on its local X, Y, and Z axes.
- Heart Size Multiplier: Global scale (XYZ) applied to the heart.
- Heart Facing Rotation: Angular rotation (local Z-axis) of each heart at its origin.
- Heart Z Offset: Z-axis displacement of the heart layers. Negative values intersect with Z=0 (cut plane), generating a flat bed adhesion area.
- Heart Radial Offset: Radial displacement of the anchor line. Negative values increase volumetric intersection with the base.
- Lateral and Vertical Overlap Factor: Interpenetration rate between adjacent instances.

TECHNICAL SPECIFICATIONS & PRINTING
---

- Clean Printing Base: The parametric bottom is cut perfectly flat on the Z-axis, ensuring maximum bed adhesion without the fragility of the heart tips.
- Support-Free: The design ensures progressive overhangs without the need for any supports in FDM printing.
- Premium Finish Tip: For a wonderful textured ceramic look, enable the "Fuzzy Skin" option on the outer contour in your slicer!

RECOMMENDED PRINT SETTINGS (Bambu Studio / OrcaSlicer)
---

- Layer Height: 0.16mm (Optimal for the vertical curves of the spheres)
- Wall Generator: Arachne (Recommended for filling small fusions)
- Infill: 10% Gyroid or Cross Hatch
- Supports: No supports needed!
- Fuzzy Skin (Optional for premium finish): Contour, Thickness: 0.3mm, Point distance: 0.8mm

💡 Pro Tip: Enable Variable/Adaptive Layer Height in your slicer.
