Custom 3D Printed Cooling Case for Raspberry Pi 4B

The Raspberry Pi is a compact, low-cost single-board computer designed by the Raspberry Pi Foundation. Its goal is to promote computer science education and provide an affordable platform for tech enthusiasts to experiment and innovate. Despite its small size, the Raspberry Pi packs significant power, supporting various operating systems like Linux and even lightweight versions of Windows.

Use Cases:

• Education and Coding: A great tool for teaching programming and computer science, especially for beginners.
• Home Automation: Powers smart home projects, such as controlling lights, appliances, or security systems.
• Media Centers: Can be used to create a home media server with applications like Kodi
• IoT Development: Acts as a hub for Internet of Things (IoT) projects, enabling interaction with sensors and devices.
• Robotics: Perfect for building and programming robots, thanks to its GPIO (General Purpose Input/Output) pins.
• Web Servers: Hosts simple websites or development projects.
• Gaming: Used for retro gaming emulators to relive classic arcade games.

Its affordability, versatility, and active global community make Raspberry Pi an essential platform for innovation and creativity.

You know the Raspberry Pi – tiny, mighty, and always up for a tech challenge. But sometimes, this little marvel gets all hot and bothered, like it's trying to audition for "Hot Ones." That's when the cooling system steps in, like the Pi's chill buddy.

Heatsinks? They're like Pi's spa treatment—calm, cool, collected. Fans? They're Pi's hype squad, always keeping the vibes breezy. And while you could let your Pi freestyle the heat, it'll start slow-dancing into "thermal throttling mode, " compromising performance. Not cool, Pi. Not cool.

Bottom line: If you're pushing your Pi hard—streaming 4K videos, running AI models, or even overclocking—give it a cooling system. It'll thank you by staying frosty and running like a champ. So, save the Pi, save the day—because even computers need a chill pill sometimes! 😎

So, in this blog, I'm going to show you how you can make your first 3D-printed cooling case for Raspberry Pi.

3D Model Development:

First, we need a better 3D print case for our project and that should contain lots or holes to get better air ventilation.

Here is my 3D mode, I have referred to this design from Thingiverse and this is one of the simple and good case with better airflow.

As you can see here there are lots of airflow vents and access for one big air cooling fan.

Next, we need to print our model but the issue is as a beginner, I'm not sure about print settings and other parameters. So, I just used JUSTWAY, you may have heard the same name PCBWAY. But JUSTWAY is service provider an the are providing all the hardware prints like 3D and CNS.

Final Product and Assembly:

JUSTWAY's service has been exceptional. Their customer support team was responsive and helpful, ensuring all my queries were resolved quickly. The delivery was also on time, and the packaging was excellent

My experience after placing the order was smooth and satisfying. I was kept updated about the status of my order through timely notifications, and the product arrived in perfect condition. The entire process was hassle-free.

You just need to put your Raspberry Pi inside the case and attach the cooling fan to the top base. That's all no screw is needed

Testing:

Now let's test the Raspberry Pi's temperature with the case and without the case and fan. For reading the temperature I'm going to use this simple python code.

import os
import time

def get_cpu_temperature():
    temp = os.popen("vcgencmd measure_temp").readline()
    return temp.replace("temp=", "").strip()

if __name__ == "__main__":
    # Define the duration and interval
    duration = 300  # 5 minutes in seconds
    interval = 2     # Interval between readings in seconds
    
    print("Monitoring CPU temperature every 2 seconds for 5 minutes...\n")
    start_time = time.time()  # Record the start time
    while time.time() - start_time < duration:
        # Get the CPU temperature
        cpu_temp = get_cpu_temperature()
        elapsed_time = round(time.time() - start_time, 2)  # Calculate elapsed time
        print(f"Time: {elapsed_time}s | CPU Temperature: {cpu_temp}")
        time.sleep(interval)  # Wait for the next interval
    
    print("\nCompleted temperature monitoring.")

With the case and cooling fan, here are the ideal temperature readings.

Here is the ideal temperature without the case and the cooling fan.

Next, let's try the load test.

Here are the temp readings.

Next, let's do the same test with the Cooling fan + case.

Here are the temp readings.

Look like our fan and case are working.

conclusion

crafting a custom 3D-printed cooling case for the Raspberry Pi 4 is not just a practical solution to overheating—it's a creative way to elevate your tech game. With precise design and functionality, this cooling case ensures your Pi stays frosty under pressure, whether you're coding, gaming, or exploring advanced projects. Plus, the ability to tailor your case with 3D printing opens up endless opportunities for customization and innovation.

From improved performance to extended lifespan, adding a cooling case is a smart investment in your Raspberry Pi setup. So, gear up, design your perfect case, and keep your Pi cool—because great ideas deserve a platform that runs just as smoothly as they do. Stay cool, stay creative!
