Back
Fold in half along the fold lines,
glue together at the back and make a ring.
Adding curves to the part first will make it
easier to form a ring.
After gluing parts M and N together back to back,
attach the ring you have made.
Follow the same process to assemble G, H and I.
Assemble the axle
Add curves by pressing and rolling it
against the corner of a table,
with the printed side face up.
Fold the edge to make a triangular prism,
and roll the piece up to form a stick
(about 4mm wide)
.
Wind part E around and glue it down.
Glue down the end after rolling.
Cut three, equally-spaced slots in both
ends of part D, up to the red valley fold line,
and bend them back.
*The fine strips of paper are thick and hard
so be careful of paper cuts.
Glue
Attach part L, enveloping
it around the parts you cut
and bent back.
Attach the other side too.
Attach part P to both ends.
Follow the same process to
assemble the other axle.
