This project is a parametric decorative Bubble Tray. Fully programmed in OpenSCAD, it features an elegant border made entirely of perfect spheres. The design utilizes a flawless vertical transition between the base and the spheres, eliminating any empty gaps or flat triangles at the absolute bottom (Z=0), ensuring an impeccable fusion finish.

---
UNLIMITED CUSTOMIZATION
---

The mathematical model automatically scales and calculates the entire distribution of spheres along the perimeter, ensuring accurate tangency and spacing regardless of the chosen length, width, or sphere radius. With support for 1 to 6 layers of stacked spheres, the combinations are virtually endless.

PARAMETER GUIDE
---

1. Main Dimensions
- Tray Length and Width: Defines the overall size of the round shape.
- Base Thickness: Controls the height of the solid internal bottom plate.

2. Sphere Geometry (Advanced Settings)
- Sphere Radius: Defines the diameter of the spheres and, consequently, the thickness of the outer wall. Change this to achieve anything from delicate small spheres to massive giant spheres. The model recalculates the required quantity automatically.
- Height Ratio: Adjusts the height of the containment border relative to the sphere radius.
- Overlap Factor (Penetration): Controls how much the spheres intersect each other laterally. The default (0.20) provides the optimal visual balance and structural strength.

3. Sphere Layers (Towering)
- Number of Layers: Create anything from a simple flat tray (1 layer) to a deep basket-style tower with up to 10 perfectly stacked layers.
- Vertical Overlap Factor: Controls the mathematical fusion between upper and lower layers (recommended: 0.40).

4. Customization and Details
- Bottom Logo: A dedicated space to deboss your brand/logo on the smooth bottom face.

TECHNICAL SPECIFICATIONS & PRINTING
---

- Clean Print Bed: Unlike other beaded models, this project's base is mathematically flat with no angular cuts on the spheres touching the build plate.
- Support-Free Design: The sphere geometries are calculated to guarantee a progressive overhang angle easily handled by modern printers. No internal or external supports are required!
- Premium Finish Tip: For a truly professional, textured clay or ceramic look, enable the "Fuzzy Skin" feature on the Outside walls only 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.
