ZK-502L amplifier case

ZK-502L Amplifier Case

This is a compact 3D printable case designed for the ZK-502L audio amplifier module. The enclosure protects the amplifier board and makes it easier to mount or use in DIY audio projects.

The case provides openings for the connectors, control knob, and wiring, while keeping the module securely in place. It is ideal for building a small desktop amplifier, speaker project, or portable audio setup.

The design is simple, sturdy, and easy to print without complicated supports.

The mounting holes for fixing the amplifier board are not pre-made in the model. They need to be drilled after printing to match the exact hole positions of your ZK-502L module.
