3D Printed Power & Brain Case for Raspberry Pi 5 Smart Bike

**Presenting a custom-designed, dual-purpose 3D printed enclosure system, created by Amir Mobasheraghadam for the ultimate Smart Bike project!**

This isn't just a simple box; it's a robust, integrated housing solution specifically designed for the smartbike_Raspberry-Pi-5 project. It features two critical components that work together:

1. **The Power Base:** A custom-fitted **box for a Milwaukee 18V battery**. This allows you to use powerful, widely available tool batteries to run your Raspberry Pi 5 project for extended periods, far beyond what standard power banks can offer.

2. **The Brain Housing:** A precisely designed **enclosure for the Raspberry Pi 5** that sits securely on top of the battery box. This protects the single-board computer that runs your smart bike's software, including the Streamlit dashboard, audio system, and event logging.

**🛠 Engineered for the smartbike_Raspberry-Pi-5 Project**

This physical case is the perfect companion to the software found in the **[GitHub Repository: https://github.com/Amirmobash/smartbike_Raspberry-Pi-5]** . It's built to house all the hardware needed for features like:

* **Streamlit Dashboard:** Space for a small display.

* **Audio Handling:** Accommodations for a speaker or microphone module.

* **Event Logging & Sensors:** Internal room for the Pi 5, cables, and sensor breakouts (GPS, accelerometers, etc.).

**✨ Key Features of the Design**

* **Dual-Box Stacked Design:** The Milwaukee battery securely clicks into the bottom box, which has a flat top to perfectly host the Raspberry Pi case above it. This creates a single, portable power-and-processing unit.

* **Perfect Component Fit:**

* **Bottom Box:** Designed to snugly hold a standard **Milwaukee M18 battery**, with openings for the battery contacts to connect to a voltage regulator or buck converter (not included) to safely power the Pi 5.

* **Top Box:** Precision cavities to securely hold the **Raspberry Pi 5** board.

* **Functional Port Access:** Cutouts for all essential Pi 5 ports—power input (from the battery below), USB, HDMI, GPIO, and micro-SD card.

* **Durable for the Road:** Designed for printing in tough filaments like **PETG, ABS, or ASA** to withstand bike vibration, dust, and outdoor conditions.

* **Easy Mounting:** The combined unit can be easily mounted to a bike frame using heavy-duty zip ties or industrial-strength Velcro through integrated slots.

* **Ventilation:** Subtle channels to help keep the Raspberry Pi 5 cool during operation.

**📦 What You'll Need to Build**

* This 3D printed case set (STL files).

* Raspberry Pi 5 (with your choice of heat sink/fan).

A *Milwaukee M18 Red Lithium Battery**.

* A DC-DC buck converter (to step down the 18V battery output to a stable 5V/3A for the Pi 5).

* Your chosen display, sensors, and audio hat for the smartbike_Raspberry-Pi-5 project.

* Filament (Recommended: PETG or ASA for strength and weather resistance).

* Small screws (M2.5) for securing the Pi (optional) and wires for the power connection.

**🖨 Recommended Print Settings**

* **Layer Height:** 0.2 mm

* **Infill:** 30-40% for structural strength.

* **Supports:** Likely needed for the battery retention clips and port cutouts. Check the preview in your slicer.

* **Material:** PETG or ASA/ABS is highly recommended for outdoor use on a bicycle. PLA may warp or become brittle in sunlight and heat.
