A compact mounting plate for the Sinilink XY-AS21HPA 2.1 amplifier board.
I designed this because I couldn't find a mount for this board.
The plate matches the amplifier footprint at 124 × 124 mm. The board sits on a flat platform with cutouts for protruding components, so nothing on the underside shorts against a table, a shelf, or the enclosure floor.
It is intentionally a raw, unfinished model. Use it as-is, or treat it as a starting point: add walls, a lid, cable exits, and turn it into your own enclosure.
Versions
Two mounting options are included.
Pin version
The board locates onto printed pins. After installation, the pins can be heat-staked (melted with a soldering iron) to lock the PCB in place permanently.
Screw version
The board is fastened with M3 screws. 4–6 mm length is enough.
Both versions keep the same outer size, so you can start with whichever mounting method you prefer and still build a case around it later.
Why this exists
A bare amplifier board should not sit directly on a surface. Capacitors, solder joints, and the underside of the PCB are easy to damage or short.
This mount gives the board a stable, insulated platform without committing you to a specific enclosure design.
Intended use
Place the amplifier on a desk, shelf, or inside a prototype box without worrying about shorts
Build your own case on top of this plate
Remix the model: add side walls, a front panel, ventilation, or mounting ears
Feel free to modify it. That is the point.
Printing
The model is a simple flat plate and should print without supports.
Recommended starting point:
Material: PETG (or PLA for a prototype)
Layer height: 0.2 mm
2–4 perimeters
100% infill
Hardware
Pin version: none (optional: a soldering iron to heat-stake the pins)
Screw version: M3 screws, 4–6 mm long
About the "Yet Another..." Series
The Yet Another... series is a collection of practical models created to solve everyday problems in my own workflow.
Most of these ideas already exist in one form or another — but I couldn't find one that worked exactly the way I wanted. So I designed my own.
If you find these models useful, feel free to check out the rest of the series.
