Bluetooth Speaker
myminifactory
Simple and affordable portable Bluetooth speaker! I utilized a SANWU CSR8635 audio board powered by a 18650 battery. The charger board was a TP4056. I had the battery, the charger, and two 34x34mm miniature speakers already in my possession. To assemble the speaker, I used small 3mm screws and hot glue. For the front grille, you can use any material of your choice - I simply cut and glued the one shown in the picture. Another option is to repurpose a metal box from a Jack Daniel's bottle, which can be found at most stores. P.S. I also drilled a hole for the LED light, but it is not necessary if you print the buttons with clear filament.
