3D model description

I needed a lot of tiny linear actuators so I designed something like this.In most cases all the parts required to build this can be found in computer optical drives, but I also added a version with linear bearings instead of brass bushes(not all drives have them).The linear bearing version is better in my opinion but both work well.Parts needed from cd/dvd drive:
-3mm shaft
-linear stepper motor
-slide bushes (if there are no brass slide bushes in the drive, use 2 LM3UU bearings)
-M3 screws

You should use glue on parts placed on shaft (clutch and nut).In some stepper motors the holes must be enlarged to fit M3 screws

How it works: https://youtu.be/nML0P0cFWjI
