This was a little project with my daughter to activate her maker genes. We got the "ArliKits AR190/B Electronic Cube with 7 Blue Flashing LEDs Giant Fun Electric Cube Replacement Simple Soldering Kit" from Amazon that she had to assemble and solder herself.

After that we started to build the case.

You can find the result here :-)

Because there was no switch included in this kit, I got these switches at Amazon

HUAZIZ 25 pieces Mini Slide Switch Vertical Foil Switch 3 Pin 2 Position 1P2T SPDT with PCB Panel for Arduino 2A, 125V DC, 5mm

With some fine work with the file, we then fitted the switch into the housing

Have fun :-)
