I thought about this on my laser project... It has a telescoping piece that lets you move the focusing lens up and down, it would be pretty easy to do. I can move it by hand though, and I think that's what I'll go with for the time being.
I love how he used a paperclip as the lead-nut. It's definitely a creative/resourceful design.
