We’ve seen teeny-tiny 3D printers before, and now we’re getting pint-sized creations to match. An ingenious engineer from New Zealand set out to make the world’s smallest cordless drill, and the result is pretty remarkable. The tiny tool measures just 17mm tall, 13mm long and 7.5mm wide, with a 0.5mm twist drill that can pierce soft objects.

Perfect gift for the Barbie or Ken in your life?
