Sonic Trowel (LED)

cults3d

Here is my version of Sonic Trowel from Dr Who designed for a friend. There are two versions: regular one and LED version. For the LED, use 3mm blue LEDs, a micro on/off switch, and CR2032 3V batteries. There is enough room inside the handle to put a battery holder, feed the wire through, and connect it to the LED. The two pieces of the handle fit together snugly, allowing you to change the battery when it's flat.
