Straight (No Wobble)
5/5
Like another reviewer, I purchased two steppers from another (robotdigg) vendor with bent rods. Took a chance and purchased two of the 350mm length units from Spool3D. A BIG 5 STARS for sending me absolutely straight rods. Completely eliminated the z wobble I've been fighting with. VERY HAPPY!
Only wish Spool3D offered longer (straight) versions say 400mm rods for another printer I have.
