Simplest Raspberry Pi 3B/3B+ Case

⚠Note

A v2 has been released, featuring a more secure lid that is less likely to come off, and improved fit that makes installation easier without the need for sanding.
While v1 is still available for download, v2 is recommended in most cases.

Version 2

This is a very simple Raspberry Pi 3B/3B+ case that can be 3D printed without supports.
It’s designed so that most heatsinks can be used without issues, while keeping the gaps around the external ports as small as possible.
For a cleaner look, there’s a version with vents only on the sides, and for applications that need better cooling, there’s another version with additional top vents and a cutout for the GPIO header.
