Expanding Itchy: Mostly Victorious

Well, those lead screws didn’t need to be that long anyway.

Wait, they did? Oh. Well, let’s cut about 5mm out of this solid block of aluminium and add in some washers … there…

If necessary, I can put the solid block of aluminium on the other side of the metal it’s attached to right now, and that’ll tighten things up, although I’d need to take some more length off the lead screws. That could never go wrong.
