Step 9: Attach towers to clusters
Attach each tower to its cluster first. Then attach the assembly to the nut in the base plate slot (Step 10).
Put an M3x6 mm screw through the tower and into the square nut in the cluster. Tighten it a little to keep the cluster roughly in place. You adjust it later.
Make sure each tower goes in the right place:
- Thumb: the acute-angle tower, long side down.
- Index fingers: the tall oblique tower, tall side up.
- Middle, ring and pinky: the shorter, symmetric towers.
