Folding Diagrams for Jasper's Box p. 3 of 3 (Steps 24-29)
There is a 135 degree angle formed by the edge of the interior flap,
and the top edge of the box (precreased in step 17.)
Lock the interior flap by bisecting this angle.
Note: If the flap cannot be locked by bisection,
lock the flap by folding it over twice.
Avoid raising any paper above the horizontal crease made in step 17.
Repeat steps 22-24 on the other three interior flaps.
Make a "shelf" by
the lip of one side of the flap.
The lower part of the lip (the triangular shelf) will lie parallel
to the base of the model.
Repeat step 26 on the other three sides.
Interlock the four flaps.
The finished box. The box can be opened and closed fairly easily.
