Linear Bearing Alignment Tool

thingiverse

I made 3 simple alignment tools and clamped them to the Y axis rail, then pressed the bearing rail against them while tightening the screws down to fix the rail in place. This eliminates the need to measure the distance between the side of the rail and the V slot extrusion, saving a lot of time. I've only used this method for my Y axis alignment so far, but it can also be applied to aligning linear bearing rails on the X and Z axes if needed.
