Summary This lamp is inspired by the snake puzzle game. with the right power source (3[V] x[A]) you can make it as long as you want. the lamp can be oriented in any way and will stay constantly on. The "conductive ring" pieces must be made out of metal or highly conductive filament (in the prototype they are PLA coated with tinfoil). Each cube contains 4 leds, all mounted in parallel. the positive pole will touch the inner ring while the negative, the inner one. In the cube there are tunnels where the wires pass through to connect the rings on the two sides. the electrical socket is of the type present on Arduino (the one used for 12V] usually). the lamp is held together by an elastic cord. the locking system is identical to that of the previously loaded snake puzzle cube
