Snowflake 3D Ornament Spherical

Dimensional snowflake has twenty “crystal tips”: 
six radiate from modified hexagon center; 
double-tip cross arm fits through middle slot; disc and half disc 
interlock with cross arm to hold a dozen flake tips. 
All components are composed of approx. 8 card stock layers, 
glued up and pressed flat while drying, to fit together 
and attach like laser cut Baltic birch. 
(Project model shown uses one color cardstock for core, 
contrast for front and back of each component.) 
Punch hole included for ribbon or twine loop to hang 
as ornament. 
Measures 5.5” diameter.

ASSEMBLY: 1. Identify and cut the shapes.
Refer to Step 2 to determine how many layers will
fit into the test slot, then cut out that many total shapes
for each of the component shapes shown here
(NOTE that the model project uses a contrast front and
back with 6 core shapes between for a total of 8):
A main whole snowflake with hanging punch hole
B double-tipped center arm
C individual snowflake tips - 12 units required
D center circle (NOTE this shape has been modified)
E left and right half circles
2. To determine how many layers should be cut from
the card stock paper that you are using for this project,
cut the TEST SLOT shape and 8-9 rectangles to
layer and check for fit in the slot.
For the model project, front and back are cut from
contrast as shown, with interior core shapes.
Stack the rectangles as they will be layered into
components, and fit into the slot . . . 
. . . adding or subtracting a layer to determine best
fit. The stack should be able to fit freely into the slot,
but with enough leeway to allow for the glue that
will attach the layers together when real shapes
are stacked and glued together.
For instance, NOTE the double-tipped center arm
layers, shown here (NOTE the slot in this prototype
has been modified back to a simple slot in final file).
3. Layer each of the components and glue the layers
together, taking GREAT CARE to align all cut edges
as precisely as possible throughout.
Pay particular attention to the alignment of edges
in the end notches or slots so that the components
will fit together once they are glued up and dried.
Quickly add the shapes, one by one in order, then . . . 
. . . press glued-up shape under a flat heavy object
such as this fabric-covered repurposed free weight shown
here, or a section of a plank, or heavy book, until
completely dried. NOTE: this will take several hours
to press flat, which will help prevent curling or warping
of the glued up shapes.
Shown here is a nearly side view of the main
whole snowflake shape which has been glued up
and pressed, allowed to dry, and is now ready
for assembly.
Here, all components are shown glued up and ready.
4. Begin assembly by inserting the center circle shape
into the center slot of the double-tipped arm shape,
and push halfway through the slot until center guide notches
align at the slot. 
NOTE: make sure the circle center and
the center slot of each stay aligned (indicated by
edge notches in the finished cut file shape);
the mid-center dash marks will help align the assembly
with the main whole snowflake later).
Apply glue to lock the edges together, if desired
(here and throughout).
5. Take note of the six-arm slot of the main whole 
snowflake, then "flex" or squeeze the assembly from
step 4 above to replicate that 60 degree angle.
Insert one end of the double-tipped assembly into
the slot as shown . . . 
. . . then slide into halfway-through position where
the mid-center cut guide marks will align at slot middle.
6. Insert one of the half-circle components into one of
the remaining open slot positions and slide through
to the halfway position, using cut guide marks to assist
with final alignment. Then . . . 
. . . repeat for the final semi-circle and open slot.
Here is the assembly so far.
7. NOTE: the remaining assembly where tips are
positioned and attached will REQUIRE gluing in place.
Recommendation: use a quick-grab clear glue such as
the Fabri-Tack shown here.
Apply a dab of glue into one of the notches at center 
circle edge, then . . .
. . . position the notched end of a snowflake tip at
a right angle to the circle's notch, and slide together
completely. Quickly make adjustments so that arm is
straight, slots are completely pushed together,
and visualized centerline on same plane as circle.
Then allow to dry. Continue to position and attach
the remaining 11 individual arm shapes in same fahsion.
Here is the completed spherical snowflake ornament.
Add decorative twine, ribbon, string, etc. as hanger.
Here is the completed ornament hanging from
an ornament hook/stand for display.
