The world’s smallest 3D printer can fit in your wallet, but still works

A hobbyist YouTube channel for “technological experiments” is the driving force behind the My N Mi, which claims to be the smallest and lightest 3d printer In this world.

At 18 x 31 x 41 mm (0.7 x 1.2 x 1.6 in), it’s about as tall as a matchbox and as wide as an SD card adapter (according to my N Mi’s own comparison), and weighs just 17 grams (0.03 lb) . This is not just a hoax.
