Raspberry Pi case for 3B / 4 / 5

Sharing my creation, yet another raspberry pi case for both Raspberry Pi 3B and Raspberry Pi 4. There's plenty of ventilation to allow the pi to cool and the cover includes a slot to snap in a 30mm x 30mm x 7mm cooling fan. You can buy the fans on amazon for about $10 for four.

Update: Mar 17, 2024

I've added a RPi 5 version and I've also posted all of these models on Printables.
