Why the Raspberry Pi 3B/3B+ in 2026?

Although the Raspberry Pi 3B is an older model, it remains a very affordable and powerful workhorse for many home server tasks, such as Pi-hole, lightweight web servers, home automation controllers, network monitoring, NAS devices, and more. This case gives your affordable device a sleek and modern look.

Cooling Options

• Blower Fan: Originally for Raspberry Pi 5 (Model 3007) size: 30x30x7. More information about the connection can be found online (4-pin fan raspberry pi 3b etc.).

• Traditional Fan: Use the alternative model or cut the hole (marked circle)

• Passive cooling: for light server tasks, a fan may not even be necessary.

Printing Recommendations

• Material: PETG or better material is highly recommended if your Pi runs hot or operates 24/7, as it handles heat better over time. PLA is an excellent choice for a decorative finish (especially matte or wood filaments) if the temperatures stay moderate.

• Resolution: 0.2mm for a clean look.

• Supports: Everywhere (see the photo for recommended placement)

  

How to open the case if needed

• Pry the case open with a pencil near the USB port.
