Wow, what a great response. Thanks everybody ;D (says the proud father)
But just now I re-read my post and realized I could have added some more details.

what are you using to control it?
Its just a simple two 555 timer (556) circuit. This page explains how.

You can do it with one 555, but I thought I may have trouble reaching both ends of the servo.

Looks like a lot of time went into that awesome build...
About a month.
And nice avatar Jay. Seems theres a few of us here.

I assume that this is the "more impressive build" that you saved to house the 6x... Very, very nice!!! I love it! Again, great work wolfblue! +1 for this!
This is the one you asked to see Jakob. And thanks for the +1

Are you using an Aixiz module ?
Is 3" to infinity focus done in one turn ?
Its a Meredith block with acrylic like this.

And the lens probably rotates 120 degrees for that focus range. With the lens sitting close to the diode like the Meredith does, thats all you need. With a Aixiz I would think you may need a lot more. The hobby store did not really have suitable R/C car gears for that ratio. Plus the Aixiz is a little wobbly. It has to be solid or it would jump gears, so the focus gets out of the normal range.

Nice Idea, i like that you put complete power supply in it with the batteriesl

I'm guessing that is what the other pot is for. I've been contemplating a XYZ position control with servo focus and a wired remote.
One pot for Power, one for Focus. And I considered a x/y servo aiming type thing. It would be easy with a 2 pot joystick. .But slow.

Yet another idea I will need to try
Regards rog8811
Except you'll build something REALLY COOL. With a pager motor.
Also, it has 3rd 555 timer and relay for the 3 second on delay. I meant to add a manual internal shutter. But I may have room for another servo and one more 555 timer. The pcb was done with dry transfer pads, and a Sharpie pen to draw the traces. And etched an drilled and so on.
And thanks Dr.Laser....
