This is a simple and modern case for single-board-computers like the Raspberry Pi Model 3 B+.There are multiple top's included, which have different configurations of openings. Additionally only four screws are needed to fix the SBC to the lower shell.
supported models (not guaranteed):
Raspberry Pi Model 3 B+
Raspberry Pi Model 3 B
Raspberry Pi Model 2 B+
Raspberry Pi Model 2 B
Raspberry Pi Model 1 B+
... and many more, with the same dimensions.
If you coincidentally want to use this case for a Libre Computer "Le Potato" here is my special design for this SBC.
only my example, but would reccomend 0.1mm layer height, printing it with the largest flat side oriented down
