This project is a protective two-piece case (threaded base and lid) for lip balm sticks. Fully parametric in OpenSCAD, it allows for precision adjustment for different brands and deep aesthetic customization.

UNLIMITED CUSTOMIZATION
---

With over 30 texture patterns, 5 connector options, and adjustable scales, this project offers more than 1,000 unique combinations for you to create an exclusive case.

PARAMETER GUIDE
---

1. Keychain Settings
- Add Connector: Enables or disables the attachment point on the top of the lid.
- Connector Type: Choice of geometries (Loop, Heart, Flower, Circle). All feature a 4mm internal hole with 0.6mm chamfers for easy fitment of metal rings.

2. Aesthetics and Texture
- Surface Pattern: Applies geometric textures in high/low relief to the outer face.
- Pattern Depth: Controls how pronounced the texture is (recommended: 0.6mm).
- Pattern Scale: Adjusts the size of the texture tiles. 

Scale effects on the same pattern

Small variations in this scale dramatically transform the visual effect, essentially creating entirely new textures from a single base pattern.You can fine-tune the look from bold geometric shapes to fine, intricate details.

- Logo Patch: Creates a smooth, centralized area on the base for logos or custom labeling.

3. Lip Balm Measurements
- Stick Diameter: Enter the actual measured diameter of the lip balm.
- Air Relief (Internal Clearance): Extra space added to the diameter. The recommended 4.0mm value is essential to prevent a vacuum effect, allowing air to flow so the product can be removed without resistance.
- Wall Thickness: Controls external robustness. The overall diameter is automatically calculated to maintain this thickness regardless of the hole size (Minimum: 2.0mm).

TECHNICAL SPECIFICATIONS & PRINTING
---

- Support-Free Design: The lid features a 45-degree internal chamfer at its roof. This eliminates the need for internal supports, ensuring a clean finish and immediate functionality after printing.
- Threading System: Optimized metric threads with custom tolerances, ensuring a smooth and firm closure.
