I didn't have a spring at the right size, so instead I used a nylock at the bottom, and just 2 Ø4 washers, so the "leadscrew" doesn't float top to bottom. I also used a little bit of heat to recess the 2 washers, as my M4 bolt was -just- long enough to capture the nylock. runs very smoothly and very stable. great design!

I don't use optical end-stops but this looks fascinating, do you have a video of it working?
