STEP 20
Next, find the next two components that make up
our gripper assembly. These identical pieces will
make up the second portion of the fingers of our
gripper. They will be connected with an
M3 x 10 mm bolt and an M3 nut (Figure
7-20

attached, using an M3 x 10 mm bolt and an M3
nut (Figure
7-21
).
