Amplifier Case
thingiverse
The 2x25 watt audio amplifier board, available from Parts Express (http://www.parts-express.com/2x25w-@-4-ohm-tda7492-class-d-audio-amplifier-board-only--320-332), comes with Solidworks files. To assemble the case, print two halves at 0.2mm layer thickness and 100% infill; alternatively, use 2 extra shells and 25% infill. Assemble the parts using four 3mm dia, 10 to 16mm long flathead machine screws. Mount it on any surface with small Pan Head screws. Note that this case is compatible with the unmodified amplifier board; modifications like adding screw-terminals may affect its fit.
