It is understood that the entire print object without any support mechanism, he will be micro drill is divided into three parts, all printed out, spent a total of 25 minutes. Although 3D printing is really easy to do, but the assembly does not seem so easy. The three sections include a chuck with two outer housings and a fixed motor shaft. The Abernethy uses the battery on the hearing aid as a power source, and installs a small button and a micro motor. In order to solve the wiring problem, he peeled off the headphone cord and used it. In order to assemble the drill, Abernethy spent more than 3 hours of time, because in the connection process, the wire is always broken, he must try to do them fixed in one place, but also to avoid the short circuit of the battery, it sounds too painful, this is a nightmare!
When all the work is completed, a mini electric drill was now in front of you, it is only 17 mm high and 7.5 mm wide, 13 mm long, and has a 0.5 mm drill, can be drilled through the soft objects. It is said to be the smallest electric drill in the world, completely written into the Guinness book of world records.
