World's smallest power drill created using 3D printer

A man in New Zealand has used a 3D printer to create what may be the world's smallest working power drill at just 1.3cm long.
The cordless tool designed by Lance Abernethy has a motor and battery and can drill through soft objects.
Abernethy decided to make the world's smallest working drill, so he set about creating a 3D design, using the outline of a normal drill as a reference.
He then 3D printed the plastic casing and then the drill "chuck" which is pressed into the motor shaft.
The tiny drill measuring 1.7cm high, 0.75cm wide and 1.3cm long is powered by a hearing aid battery, has a small button and a miniature motor, according to 'mirror.Co.Uk'.

Abernethy borrowed wiring from a headphone cable.
Getting all the components soldered together took him three hours, Abernethy told '3Dprint.Com'.
"The wires kept on breaking off when I was trying to connect them and it was a nightmare trying to hold them in place and try to not short the battery," Abernethy said.
