TPA3116 Power Amp case

thingiverse

This is a compact enclosure designed specifically for small TPA3116 power amplifier modules widely available on eBay. These modules come in various configurations, and I personally use one with a small footprint, as shown in the accompanying picture to help match against similar listings on eBay. It features a sliding lid that provides easy access to securing power and loudspeaker connections via pre-drilled holes. The OpenSCAD file offers customizable options for audio input openings. You can choose between a front panel access for the onboard jack plug or a rear panel for connecting through onboard jumpers, or even both configurations simultaneously. The rear opening can be positioned in the center or offset to one side, allowing for optimal placement without obstructing screw holes. The accompanying picture depicts a central rear audio setup.
