MH-M38 bluetooth amplifier case

A remixed case for MH-M38 bluetooth amplifier with speaker connectors. With the original design my M38 didn't positioned correctly, and the USB connector and PCB could only fit in at an angle. On top of that, the speaker wires broke when I closed the lid, so I made a taller lid, adjusted the USB port, closed the side hole I didn’t need, and drilled holes for the cheap, spring-loaded (red-black) speaker connectors available at the store. My M38 panel fit perfectly, but while I was screwing it in, I held the PCB in place too tightly and broke off the USB connector. Be careful with this!
