This is a mod on my other Octoprint Ready Case
This fits Raspberry Pi's from the 2 up including 3B and 3B+
This one has a mount for 2020 series rails on the end with a cutout for SD card access, if you need it.
This is a roomy case with plenty of space for wires and cooling plus a large 60mm fan on top. It has access to all ports and you can use DuPont or other header connectors inside easily.
Print with support!
