A very simple holder for a mini Mono-Amplifier for 15 EUR I bought on amazon because I have old big speakers I cannot get rid of. The mini amplifier is nice, but its very light and it would drop, so I created this minimalistic holder, which you can attach with screws to the speaker body. I think it is necessary to keep it open to avoid overheating of the electronics.
I am not sure if the power supply was a part of the amplifier or not, but sure you can buy one as well for some good price. And if you want to have it all wireless, just buy a Lithium battery. My battery was pretty expensive, around 50 EUR I guess, but it is 24V. I guess, the more volts you have the louder are the speakers, but it should work with a 12V battery as well - which is cheaper.
If you want to print the battery holder, make sure, you separate the 2 objects before printing - the top and the case. It is not possible to print like this.
I printed from PETG probably with supports. Not sure any more :(
