Original descriptions:
Two base pieces and one middle piece are needed for a single lead screw. An additional two M3 screws are required to hold one of the ends on the X-gantry bracket and the other with the lead screw nut.

Some slight sanding and silicone grease were required to ensure it slid smoothly in the X and Y directions but was tight enough to not have much slop in the Z direction. I printed it with Inland PLA+, but PETG might be better due to its slippery finish.

Changes:
Changed tolerances for tighter fit. Added Fusion360 project with tighter tolerance offset as parameter. (See on pics)

For me, I used one -0.15 mm and one -0.1 mm offset tight versions. Printed with 0.2mm nozzle with PLA
