Left Leg Parts

Set aside the left leg parts, keeping them separate from the similar-looking right leg parts. Hip pitch and hip roll actuators are accounted for in the pelvis checklist.

Quantities are based on the assembly instructions, not a verified shipping manifest. Check the full quantity before ticking a row; leave uncertain items unchecked.
