ZK-MT21 | ZK-TB 21 Amplifier Enclosure
Cases & Enclosures
Protective PETG case for the ZK-MT21 and ZK-TB 21 amplifier boards — desktop or mounting use with ventilation.
LEARN. MAKE. INNOVATE.
Custom 3D-printed enclosures, mounting parts, and project-specific hardware — designed around your device, printed to fit, and refined until it works. Locally designed and 3D-printed in Antipolo City, Philippines.
Real parts. Real use.
We design and print practical parts around the device, dimensions, and job they need to do — then refine them until the fit, the function, and the finish hold up in daily use.




Built to be used
A useful part comes down to the details — clearances, tolerances, material, and print orientation. We design around the device and the job, then check the fit before we call it done.
Dimensions, ports, controls, and mounting are modeled around the exact module or object you're building with.
Material and print orientation are chosen for what the part must do — not just what it looks like.
Fitment is checked on a test print, and the part is adjusted until it fits and functions how it should.
Custom printing
From a custom enclosure to a mounting bracket or project-specific part, we design or adapt a 3D-printed solution around your device and requirements — and refine it until it fits and functions.

We model around your board and needs.
A prototype confirms fit and function.
Approved design, final material, dispatched.

Projects
A look at how Elliztronics hardware is used in electronics builds, workshop setups, and comms projects — from custom enclosures to finished devices in the field.
Every project starts as a requirement — a board that needs a housing, a device that needs to be mounted, a build that needs a part. We document the parts, the process, and the result so you can see what's possible before you start.
