Rigidbot Z axis Lead Screw Nut Linear Bearing Mount

thingiverse

Updated 5-7-16. Added a new version that allows for some extra room when sliding in the bearings. The initial one kept snapping the outside leg off while inserting the bearing. I got this idea from virtualight, who turned my concept into a prototype. This remix lets the x-axis bracket slide back and forth on the rails, making up for any lead screw wobble. The screw holes are designed to allow some wiggle in the Y direction. To make it more practical, I remixed it using a shorter LM8UU Bearing so I wouldn't lose too much x-axis space. This should only cost me about 4mm on the x-axis compared to the 20mm I was losing with the longer bearings. This design is untested and I'll post an update once I've put it through its paces.
