Locate the left and right filament spool brackets, the two spool cones, the Spool Hardware bag and the spool axle (grey PVC tubing).

The spool axle is taped shut at both ends, inside you will find two pieces of wire. These will be used in an upcoming step to install the wiring harness.

Loosely attach the left and right filament spool brackets to the T-nuts on the top unit. These are in the cross members coming from the Z tower as shown in the second photo.

Install the spool cones on the spool axle as shown in the third photo. You may have to enlarge the bore in them to get a tight friction fit on the axle.

Insert the axle into the spool brackets and slide the brackets on the cross members so the axle is supported as shown in the third photo. Then tighten the four screws to secure the brackets.

Remove the axle and set aside so it is not in your way in upcoming steps.
