Engineer from New Zealand Lance Abernathy printed the most compact in the world drill using a 3D-printer Ultimaker 2.
The device, which is installed inside a tiny fee, it is working. It is able to drill a small hole in the top layer of skin of a finger or paper.
First, engineers have created a computer model of a mini-drill using the program Onshape 3D, using as a "standard" full-size drill. Then he opened the two halves of the enclosure and the chuck for fixing the "needle».
It is interesting that the whole process has been spent around 25 minutes.
Next, the engineer took about three hours to place the device in a tiny engine, the battery, the power button and wires obtained from purified headphone cable.
The dimensions of the resulting mini-drills made 17h7, 5h13 mm diameter drill - 0, 5 mm.
