Making the threads in a bottle cap

I am trying to make, essentially, a bottle cap with threads; like the on a common soda bottle for some bird feeders.

I’m using the arc tool to create a spiral, then attaching a closed half circle for the tread. When I use the follow me tool, it does create it but the half circle rotates as it goes down.

When I model screw threads I use Curve Maker to draw a helix with the proper pitch and then Eneroth Upright Extruder instead of Follow Me.

Not bottle threads but you can see the results of using Upright Extruder.


Just added them both, thanks.

Is that a Extension or something else ?

What pitch did you use ?

I don’t know why it matters but I used the pitch what was specified. In the case of that jack, it’s 2.0
