Futuristic 3D-Printable Device Enclosure

Job ID: 40365065

Budget: $30 – $250 USD

I'm looking for an experienced 3D designer to create a precise, 3D-printable enclosure for a custom handheld device. This design should be inspired by a futuristic Sailor Moon crystal brooch combined with a modern smartphone. It's important to note that this is a functional electronics housing, not just a decorative prop.

Requirements:
- The design must be 3D-printable, as I plan to use PLA material.
- The ideal candidate should have a strong background in 3D design, especially with intricate and functional designs.
- Experience in creating designs based on concept sketches and photos is preferred.

Ideal Skills and Experience:
- Proficiency in 3D modeling software (e.g., Fusion 360, Blender, SolidWorks).
- Strong understanding of 3D printing processes and constraints.
- Ability to translate concept sketches and reference photos into accurate and functional 3D models.
- Attention to detail and creativity in integrating decorative elements with functional design.

---

SCREEN DESIGN CONSIDERATION

- Screen is rectangular but must appear circular
- Design must:
- Hide screen edges completely
- Allow precise centering under 90mm window
- No modification to screen itself

---

BUTTONS (RIGHT SIDE)

- Volume rocker cutout:
- 22.5mm x 4.5mm
- Power button cutout:
- 12.5mm x 4.5mm
- Include internal clearance (2–3mm behind buttons)

---

SCREW SYSTEM

- 4x M2 screws
- Evenly spaced (90° apart)
- Radius from center: 47mm
- Include matching internal standoffs:
- Height: 6–8mm
- Diameter: ~5mm
- Hole sized for self-tapping M2 screws

---

BOTTOM HOUSING (INTERNAL STRUCTURE)

Must include organized internal layout for:

1. Raspberry Pi Zero 2 W

- Dedicated mounting area (right side)
- 4 standoffs (M2 compatible)
- Clearance under board: 2mm minimum

2. Battery Compartment

- Left side placement
- Space: 60mm x 30mm x 6mm
- Include small retention lip or support

3. Speaker Housing

- 8–12 holes
- 3mm diameter
- Positioned along top arc (~120°)
- Bottom vents:
- 6–8 holes
- 3mm diameter
- Must allow airflow path across main board

---

CHARGING PORT

- USB-C cutout
- Size: ~10mm x 5mm
- Placement: top edge or accessible side

---

ASSEMBLY REQUIREMENTS

- Two-part enclosure:

- Top shell (screen housing)
- Bottom shell (component housing)

- Must:

- Align perfectly
- Be screw-fastened (no glue required)
- Allow easy disassembly for maintenance

---

PRINT REQUIREMENTS

- Optimized for FDM 3D printing
- Wall thickness: 2.5–3mm
- Include proper tolerances:

- Avoid unnecessary supports where possible

---

FILES REQUIRED

- STL (for printing)
- STEP or F3D (for editing)

---

GOAL
Create a clean, modern, screen-dominant device that looks like a real piece of tech—not a toy. The front should resemble a smartphone surface, with all decorative elements handled digitally on-screen.

---

BONUS (OPTIONAL)

- Suggestions for improving durability or assembly
- Optional snap-fit or magnetic closure ideas
