Prusa i3 Bear Upgrade Z Rod Stabilizer Knobs

thingiverse

My lead screws were wobbling and moving inside the z-tops, which was really frustrating. This simple, tool-free mod stabilizes the lead screws and serves as a useful knob for leveling the z-axis steppers. Print one knob for each lead screw and screw them on tightly. You can expect to see pictures of this mod soon. I'd love to see what you create with this mod! Please post your makes and share them with me.
