I need to convert the rotation movement of motor to a linear move (have to be in the same axis of the motor)

I made a 3d model on tinkercad consist of 2 parts:

• first part will monut on the motor and has a shape like screw inside

• second part is a plunger that should move in linear direction when the motor rotate with the first part

I printed this model but the plunger stuck inside the first part and do not move So it fails

I want a simple way to convert the rotary move to linear in the same axis of motor

Edit:

I broke part 1 from behind to see what happened inside i found it stucks as the part 2 jump above the screw shape

I think this mechanism is hard to be done

So i switched to scotch yokes mechanism Hope it works!! The vertical gear will pull the horizontal gears to move the articulator in linear move

I need to convert the rotation movement of a motor to a linear movement (it has to be in the same axis of the motor).

I made a 3D model in Tinkercad consisting of two parts:

• the first part will mount on the motor and has a shape like screw inside

  

  

• the second part is a plunger that should move in linear direction when the motor rotate with the first part

  

  

  

I printed this model but the plunger gets stuck inside the first part and do not move.

So it fails.

I broke part #1 ("the first part") from behind to see what happened inside. I found it sticks as part #2 jumps above the screw shape.
