As you'll see from my comment on triffid_hunter's version of this, the license is wrongly tagged on this item -- the copyright notice in the .scad itself correctly declares the license as GPL v2 or later, so perhaps you'd be kind enough to fix the way that's been tagged in thingiverse so that it also shows as GPL

Mine worked sweetly just as printed from the STL. If you have .250" (6.35mm) lead screws, chances are your local hardware store has inch size tubing, like mine. I used 1/4" O.D. x 0.170" I.D. vinyl tube which measured almost exactly 7 mm when snugly stretched the motor shaft.
Triffid Hunter suggests printing with 90% infill. I used PLA.
This really improved my bottom layers (and therefore prints) by making my Z zeroing repeatable. My cheap, easily bent lead screws are now a lot more tolerable.
