Honey I shrunk the stepper! Seriously these things are tiny! Only 6mm in diameter! Have you ever wanted to put precise control into something.. tiny? Well these are the motors for you!

Note that these are definitely not a beginner motor. These motors require a steady soldering skill to connect the very small leads. You can use it to convert it to a linear translation, but you will have to find your own mating threaded attachment. The shaft is threaded with what appears to be a M1.6 thread with a 0.5mm pitch. This is a non-standard size. You can try crafting something using a low temperature thermoplastic such as Polycaprolactone (aka "Shapelock", "Instamorph", etc).
