Bob Marley LithoLamp/BT Speaker

I just smashed my old Bluetooth speaker box so I decided it was a perfect excuse to create a new one with improved features using 3D printing. I will use the board and two speakers from my old speaker https://www.amazon.com/Reproductor-JoyBox-Bluetooth-Guitar-Biwond/dp/B00T9QINWI/ref=asc_df_B00T9QINWI/?tag=googshopes-21&linkCode=df0&hvadid=54542048595&hvpos=1o1&hvnetw=g&hvrand=14740154748934819845&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=20295&hvtargid=pla-195099534795&psc=1 and add two extra speakers that will be connected in parallel https://aliexpress.com/item/32904402026.html?spm=a2g0s.12269583.0.0.71c85d24z7V4yw. I connect the speaker circuit to its own battery. The box body, cylinder, and lid were printed with a 0.2 layer height, three perimeters, four top/bottom layers at 10% infill. The speaker covers (four of them) were printed with a 0.2 layer height, three perimeters, no top/bottom layers, and 20% linear infill. The lithos were printed with a 0.12 layer height, maximum perimeters, maximum top/bottom layers, and 100% infill. The lamp was made using a five-volt LED strip around the cylinder with its own battery, charger, and switch.

The switch https://aliexpress.com/item/633310473.html and the charger https://aliexpress.com/item/32500042672.html?spm=a2g0s.9042311.0.0.274263c05GaVxL. Since I use a 18650 three-point-seven-volt battery, I need a five-volt converter for the LEDs to shine as brightly as possible.

The five-volt converter https://aliexpress.com/item/32877135108.html?spm=a2g0s.9042311.0.0.274263c06CYss6 and the battery holder https://aliexpress.com/item/33037738446.html?spm=a2g0o.productlist.0.0.59693c02apoTnA&algo_pvid=648eed73-2f61-4e2f-ae2d-4d6176350e41&algo_expid=648eed73-2f61-4e2f-ae2d-4d6176350e41-0&btsid=f06fe284-45a4-47c8-a24d-8832bfb22752&ws_ab_test=searchweb0_0,searchweb201602_9,searchweb201603_53.
