This is a case for the readily available 2.1 100w 50w + 50w amplifier module which features : MP3 WAV FLAC playing from Memory stick : Aux Input via 3.5mm jack plug : Bluetooth : FM Radio modes : Remote control
As well as the case, a few items are required :
5.5mm 2.1mm panel mount power socket
3 x speaker connectors
5.5mm 2.1mm power plug
3mm panel mount led
3.5mm Jack 15cm panel mount extension
15cm USB panel mount extension
3010 24v Fan
Laptop power supply (20v is good) with 5.5mm 2.1mm barrel plug
Materials and methods
The top is superglued to the base, the components are fitted to the rear with enough speaker wire to slide the amp into the back of the case and the back glued (i used polestyrene cement as this can be removed later).
The led may be too bright and the fan spin too noisy at the recommended 20v-24v so i fitted a 100 ohm resistor in series with the fan and a 1.4k resistor in series with the led.
The top style with the stripes is for IDEX printers.
The Base and feet can be printed as one (sometimes not as pretty) or separately. Use the guide to glue to equal placement at each corner.
