1. OctoPrint Server for Classroom 3D Printers

If your school has introduced 3D printing technology, you can transform your Raspberry Pi into a central hub for managing one or more 3D printers in a classroom by installing OctoPrint, a popular, open-source 3D printer interface. Once set up, OctoPrint allows teachers and students to upload G-code files, start and stop prints, monitor progress in real time, and even capture time-lapse videos using an attached webcam. Everything is accessible through a simple web browser on any device connected to the same network.

This setup is incredibly valuable in educational settings, where multiple students might be using shared printers. Instead of waiting in line or interrupting ongoing prints, they can queue their jobs, check printer availability, and get notified when prints are complete—all remotely. With multiple Raspberry Pi units, each printer can be given its own dedicated controller, or a more advanced setup can be created where one interface manages several printers.

Educational Value:

• Introduces real-world IoT applications: Students learn how Internet of Things devices communicate and interact through web interfaces and local networks.
• Teaches system administration basics: Setting up OctoPrint involves flashing the Pi, configuring networks, and installing plugins—valuable hands-on experience.
• Improves classroom efficiency: With real-time monitoring, prints are less likely to fail unnoticed, and students can work on other tasks while watching progress remotely.
• Promotes digital responsibility: Students take ownership of their print jobs and learn to manage shared resources without direct supervision.

If your school hasn’t yet introduced 3D design, now is the perfect time to start and a great place to begin is with the 3D Technology program from SelfCAD. SelfCAD is an easy-to-use 3D modeling tool designed specifically for education.

It makes learning 3D design accessible and engaging for students of all skill levels, without the need for complex installations. When paired with OctoPrint and a Raspberry Pi-powered print station, SelfCAD helps bridge the gap between digital design and physical creation, bringing STEM, art, and engineering lessons to life.

10. Raspberry Pi-Powered Datacenter Proxy Node

You can turn a Raspberry Pi into a lightweight datacenter-style proxy node by pairing it with a cloud-based VPS. While Raspberry Pis typically operate on residential networks, you can simulate a datacenter proxy setup by tunneling traffic through a VPS with a static IP. This allows your Pi to act as a backend proxy, while the VPS serves as the public-facing endpoint that handles requests, similar to how many commercial proxy services are structured. To achieve this, install a proxy server on the Raspberry Pi using tools like Squid or 3proxy, then create a reverse SSH tunnel or use a VPN to link it with your VPS. Incoming traffic to the VPS is forwarded to the Pi, processed through the proxy server, and sent back out. This setup not only allows your Pi to behave like datacenter proxies nodes but also gives you fine control over authentication, logging, and filtering, making it great for learning or managing custom proxy infrastructure. 

How it works:

• Set up your Raspberry Pi as a proxy server.
• Connect it to a cloud-based VPS via a reverse SSH tunnel or VPN.
• External traffic hits the VPS, which forwards it to your Pi and back — acting like a datacenter proxy.

Benefits

• Mimics a datacenter proxy setup without renting expensive proxy services.
• Ideal for learning how commercial proxy networks work behind the scenes.
