Print settings:
- for extention, long ties and bow ties, see previous posts
- x_spacer:
- material: PLA
- perimeters first
- 3 x perimeters
- 10% infill
- supports needed

Assembly:
- connect the two extentions together with 3 long ties and 4 bow ties. Then add the x_spacers to the ends of the extentions, 3 long ties and 4 bowties per spacer. Make sure the long_ties don't protrude from the x_spacer part. If they do, they will obstruct X-beam installation in next steps.

As with the Y-axis racks, the position of the rack isn't critical, the rack can be moved.
