H2 Enclosure
Many PortaPacks on AliExpress come with a metal or plastic enclosure. Enclosure dimensions, simplicity of assembly/disassembly, connector labeling (if any), and speaker hole positions (if any) varies by supplier. Some users feel that a metal enclosure is safer for devices that contain LiPo batteries.
You can 3D-print the following enclosure for your Portapack (click the pictures to get the design files):
Encoder knob:
And the following magnetic cover (consider that most of the commercial cases that clone the design of the enclosure include plastic screws, hence this wont work):
If you do not own a 3d printer, you have other options:
- Weerg for a high quality print
- 3DHubs for a low cost alternative
- Tindie another alternative, with a lot of customization options
- Injection moulded version of the case
If you need a different design, or material, check more options directly in Aliexpress.

Check the assembly.pdf from the case files for instructions.
You can easily place a small speaker inside. There is no holes in the case but it seems that the sound quality actually improves with the case: https://www.youtube.com/watch?v=XkaGV9muvbg
