[UPDATE]
There is my upgraded model with integrated limit switches: https://www.thingiverse.com/thing:5173219
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

Linear bearnigs if needed(choose LM3UU option) : https://s.click.aliexpress.com/e/_AsEc8S
