reducer for cd stepper motor

let's try to use one more time ours olds cd and dvd stepper motor for ... everything :D
you'll need one ball bearing 8x22 mm, one 8mm scew and probably something to fix it all

cut the cd or dvd stepper fixure enought to let the screw turn easily, and use glu to fix the txo parts of the stepper

edit : it's "working" ....more or less, i'll make another verion of this
