I made a pair of jigs. I made my own using the pitch of the trapezoidal screw.

Mating with the trapezoidal nut is also well moving smoothly without backlash. I think that enough precision can be maintained because it is about ten times a year. Next we plan to make it on XY table.
Nothing to use ... A few sets of precision screws and batteries are included together, and because of the large box, dry batteries were rampant and scratches adhered inside. Obviously there will not be anything precise screw side either. Three screws were fixed in the box with a curing tape. However, I pulled up and down and had it with only the central tape. I think that there is no meaning unless you pack it out thinking that you can escape! It would be better to devise a battery so that it does not go out too much. It was opened because I was in a state where it was not feeling good.
