Christmas Tree 3D Chest Countdown

 
Triangular ends give this dimensional “chest” its tree-like 
shape, with face panels each holding 12 miniature drawers 
in 3 graduated lengths to conceal a small treat, 
tiny toy, ornament, Christmas scripture or activity clue. 
Structure components are layered, stacked and glued together 
for thickness to be strong enough to last multiple 
holiday seasons, joined with tabs or end “tenons” 
that slot into walls. Windows near top provide 
a platform stage and act as carrying handle. 
Drawer fronts measure approx. 1.375” tall x 1.75” long 
x 2” wide (in 3 different depths). 
Chest measures approx. 10.9” wide x 9.27” tall x 7.22” deep 
when fully assembled. 

Add style to chest tree ends with 
“Card Tree Ginger Cookie Easel Lrg” 
(use specially prepared cookie shapes included in that file). 
(Sample project used approx. 32 sheets of card stock
 to make components thick and like craft wood panels. 
This project is recommended for paper crafters 
with experience.)

PRELIMINARIES: A. This design's assembly depends on
layering and gluing up many of the structural shapes 
to achieve a specific thickness. Cut quantities will be
determined by testing the card stock selected.
A slot test shape with small strips is included in cut file
for this purpose. Layer cut strips into a stack, then . . .
. . . slide the stack into the test slot. Stack should fit
fairly snugly. Add or substract strips until desired fit
is determined. For final test, actually glue up
the determined layers. Shapes layout
frames in step 1 below will suggest 4 layers.
Adjust this quantity to your specific solution. 
B. The sample project was being "prototyped" as
it was built for this tutorial, so some of the shapes
were modified or refined from the original design.
Other shapes were added that may not be shown
in the shapes layout images below. They ARE shown
in the assembly photographs.
C. The sample project uses a lighter face paper
and a darker core paper as a style choice.

A FEW WORDS ABOUT CARD STOCK PAPER CHOICES:
D. Stacking and gluing layers is essential to this design.
Select a good quality such as Bazille textured or smooth,
or the liquid adhesive may/will cause the paper to warp,
curl or shrink.
E. Quantities of card stock needed for this large project
make it an investment that should be understood up front.
While ensuring good quality paper, I suggest watching for
good papercraft sales from your "big box" or local craft supplier(s).
Sample project approx. quantities used: 12-13 Face color;
15-16 Core color; 2 Dark contrast; 1-2 Light contrast.

OTHER GEAR YOU MAY NEED:
F. Shown here are the adhesives used for sample project:
Tombo Aqua liquid for layering and simple glue-up
Fabri-Tac quick grab liquid adhesive for structural joints
Double-sided tape with applicator for situations where
pressing and finger pressure are restricted or unsuitable
G. Pressing flat the glued-up layers until thoroughly
dried is critical for the success of this project, a process
that will require patience and a plan. Drying may require
several hours or overnight. This image shows some of
the objects that I use to press the layered units:
thick heavy solid or ply wood panels
repurposed thick heavy book volumes
vintage-style heavy iron replica
narrow, thick plastic rulers (used in conjunction with
irons or bars to help with drawer face & rim strips)
muslin-covered repurposed free weight bars

ASSEMBLY: 1. Identify and cut the shapes:
A front & back drawers and windows panels (2 sets of 
front plus 2 underlay panels without lower array)
B edge strips left & right for edge build up thickness
C bottom bends underlay stack strips (2 sets of 
3 each in varied lengths)
D tree end panels (2 sets of 1 face plus 2 underlays)
E edge strips for edge build up thickness (2 sets of
left, right & bottom)
F slot test shapes: slot panel plus 4-5 strips

back rim reinforcement fold-over strip
SHAPES NOT SHOWN IN IMAGES ABOVE:
Crest beam (3) and connector base
Platform open area ends concealer triangles (2)
Attachment bracket strips for center wall (2)
Fingertip concealer strips for bottom shelf (2)

TIP FOR ORGANIZING CUTTING:
(Image shows Silhouette Cameo system screen)
The many shapes and multiple layers required for
this project make the cutting steps labor intensive.
Suggested procedures:
 A) opening the cutting page in software;
B) duplicating the shapes that will be required;
C) moving the shapes onto the virtual mat in
as efficient arrangements as possible, then . . .
D) once sent to be cut, moving the "done" shapes
off to an area to one side
2. Since there are 24 to build, begin with
drawer assembly. Layer the face stack with
number panel, contrast, 2 interior shapes.
Immediately press under a heavy flat object and
leave in place until thoroughly dried, for several hours or
overnight, to minimize warping or curling of glued-up layers
3. Prepare the drawer hull by bending back on all
perforation lines for panels, side flanges and
connector tabs.
4. Bend the panels back, with tabs inward, then
align plain edge at corner perforation line and join seam.
Repeat to join 3 more corner seams.
5. Insert the drawer front lower edge tabs into
slots of face plate back layer, apply adhesive to
the hull front face then bend the face panel into
position to join to hull front. Take care that finger cutout
edges align, and that consistent narrow margin of
face panel extends beyond hull sides and lower edges.
On front of assembly, apply glue to backsides of
tabs, then bend into place to attach to panel.
Immediately apply fingertip pressure to ensure tabs
and front panel attach completely.
While number face plate assembly is "curing",
it is recommended that steps be taken to assist
the hull/front panel also be pressed until dry.
Here is the set up I use: narrow pressing "blocks"
with added weight on top:
6. Position and attach the glued-up and cured face plate
assembly onto the drawer front that is attached to hull,
then press as described for front panel to hull step, above.
7. Finish the drawer by first bending the rim 
reinforcement strip back on perf line, then
applying glue and "wrapping" it over the back hull
edge and allowing/pressing to dry.
(Suggest using same pressing set up shown above.)
DRAWER FRONT & BACK PANELS
8. Prepare the front and back panels by bending back
on the narrow panel and edge flange perforation lines
(panel shape is shown face down here).
9. Position and attach the 2 duplicate (without bottom
perforation panels array) reinforcement shape on
the backside with top and side/tab edges aligned
as precisely as possible. Immediately press flat under
a large heavy weight until dry. Complete 2 panels.
10. When the panels assembly is completely dry,
position and attach the reinforcement side edge
strips, with outer edges, top edges aligned
precisely. Replace under the flat weights.
11. Prepare the reinforcement panel "rib" stacks by
layering the three matching shapes for the 3 different
strip stacks, edges precisely matched. Press flat til dry.
12. When the ribs are dry, position each in their
length-matched position (shorter in between long),
ends matched to front panel shape, and long side edges
centered between the perforation lines, and glue
in place. Immediately press flat until dry.
FLOOR PANEL ASSEMBLY
13. Begin the floor assembly by layering and joining
the two underlay reinforcement shapes with all edges
aligned as precisely as possible.
(NOTE that the final file shape has a perforation guide
line, not slots.) Next . . .
. . . position the "face" shape on top of the stack,
align precisely and glue in place. Immediately press
the stack under a large flat heavy object.
14. Position and attach the end reinforcement strips
on each end. Press under flat weight.
(NOTE this image incorrectly shows the face floor
shape unattached.)
15. Join the front and back drawer panel assemblies
to each side of the floor stack assembly, overlapping
the straight side edge of floor across the bottom flange
to perforation line, ends aligned, and glue in place.
Repeat for the second front or back panel.
16. Prepare the attachment bracket strips by bending
forward carefully along the perforation line.
The narrow flange will be vertical, and the pair will
be placed along the floor inward face at center
with enough space between to accept the bottom
edge of the center wall assembly (later).
17. Prepare a (waste)  "buffer" assembly of two long narrow
strips that will help space the two brackets 
so that center panel assembly can snugly fit. Then . . .
. . . position the first bracket next to center perf line,
with wider flange ready to glue to underside of floor
assembly. Align ends with floor ends . . .
. . . place buffer strips next to vertical flange, then
position second bracket strip (wide flange down)
snugly against buffer, and glue in place.
Remove buffer strips.
PLATFORM & CREST BEAM
18. Prepare platform face shape by bending edge
flanges forward.
19. Layer and attach the duplicate reinforcing platform
panels (2 without flanges) to each other, then . . .
. . . position the face panel on top of the reinforcement
layers, centered and with ends even, and attach.
Immediately press flat until dry.
20. When the platform stack is dry, position and
attach end reinforcement strips; press with weights.
(NOTE this image incorrectly shows the face platform
shape unattached.)
21. Prepare the crest beam strip assembly by layering
the plain face and underlay strips into a stack and
attaching together. Immediately press flat.
22. Prepare the crest beam connector strip by
bending the side long flanges forward.
Position and attach the beam stack down the center
of the connector strip, long edges even with perforations.
TREE ENDS
23. Layer and attach the face tree end shape with
two underlay shapes. Immediately press flat until dry.
24. Layer and join the reinforcing edge strip
shapes for two sides and bottom strip,
taking care that all cut edges are aligned.
Immediately press flat until dry.
25. When all components are dry, position the side
strips and bottom strip onto backside of tree panel
assembly with notched edges even. NOTE that
center top and bottom corner straight edges should
abut snugly to each other when correctly positioned.
Immediately press flat until dried.
26. If you plan to use the decoration panels for
tree ends, it may be well to assemble these, layer
and join to the tree panels while all are unattached,
to enable pressing flat while adhesive dries.
Refer to the Ginger Tree Card assembly, Step 4
for description of this step, at this LINK. Then return here.
27. Position and attach the "Optional Contrast
Underlay" shape from the card cut file behind
the decorative tree panel with icing shapes,
with contrast panel cut edges concealed. Then . . .
. . . position and attach the decorative assembly
onto face of tree end assembly.
SHELF ASSEMBLIES
The narrowest shelf unit (top) will be shown here,
but all shelves are assembled in identical manner.
NOTE that the first few shelf shapes will show the slots
for dividers prior to update which changed center 3
to be double slots.

28. Prepare the main shelf shape by bending back
the long front edge flange.
Layer the reinforcement layer (without front flange)
on backside of the main shelf shape - NOTE that
the arrow symbols point to the flange edge which
is the outward edge of the shelf.
29. Layer and join the two pair of end reinforcement
strips, matching arrow symbol direction and
all cut edges. Then . . .
. . . position and attach each on the corresponding
end of the shelf assembly, with arrow symbol cutouts
also near the outward edge/flange edge. 
 Immediately press with large flat weight until dry.
30. Prepare the long and short divider strips to create
tent-like flanges as shown (each three-line sequence
will have "valley" folds with a "mountain" fold between).
Turn the strips face down to apply adhesive between
the flanges, then press them together to create
a standing flange.
This photo shows the completed short and long
strips from front side.
31. Apply adhesive to the face side of the strip
(leaving standing flanges glue-free), then begin at
one end of shelf - with backside facing you - then
insert the single standing flange through the single slot.
Working quickly, continue along the strip to insert
each standing flange into corresponding slot until
all are in place. Invert the shelf to apply pressure
all along shelf along side of and between 
exposed flanges, until all are securely in place.
Complete the sequence by inserting and attaching
the solo flange unit into the remaining end hole.
If possible, use small blocks or anything you can think
of, with other weights on top, to apply flattening
pressure as divider strips with shelf unit glue dries.
Here is what the completed (top) shelf unit looks like.
Complete remaining 5 shelf units.
SHELVES AND CENTER WALLS
32. Attach one top wall shelf to the center wall
 at top row (toward tab'd end) of slots by 
inserting back tabs through slots. 
On backside of wall, bend the tabs downward
and glue securely in place.
(NOTE that the tabs in final cut file are longer.)
TIP: placing an acrylic ruler or equivalent tool along
the shelf edge where tabs are attaching behind wall
and applying pressure may assist with tab attachment.
33. Repeat the shelf-attaching steps to position,
insert tabs of middle shelf at middle slots row, and . . .
. . . bottom shelf tabs into bottom slots row.
(NOTE that bottom shelf final cut shape includes
finger pressure access openings near front edge.)
The prototype project included very short shelf tabs,
so a narrow strip of paper tape was placed behind/
under each shelf to assist with strong attachment.
If you believe this would assist the strength of
your project's shelves joints, do likewise.
34. Complete a second center wall with shelves unit.

35. Prepare the wall units by bending top tabs
forward, then . . .
. . . apply adhesive to the backside of one wall,
and position walls backside to backside,
align edges, and join wall units . . .
. . . taking care that the top tabs remain free.
Apply pressure to help join center walls in any
ways possible, as with other elements thus far.

36. Position the platform assembly at top of center wall
assembly with face side upward and insert tab pairs
through slots there. Bend tabs outward and glue
in place to platform face.
37. Apply double-stick tape adhesive to backside of
the concealer strip, then position (centered) and attach.
TREE ENDS ASSEMBLY
38. NOTE the crenellated high-low edges of shelves
and tree end panel edges that will be joined, then . . .
. . . apply quick grab adhesive (such as Fabri-Tack)
to apply a bead of glue along low parts of shelf ends
and also face and back narrow margins of tabs.
Immediately position and fit shelf tabs through tree
slots, working as quickly as this somewhat tricky
process will permit, until all tabs are inserted.
Double check that tree is seated firmly and completely
back into position against low shelf end edges,
then hold in place and apply pressure to secure.
39. Apply double-stick tape to backside of the two
top concealing triangle shapes, then position at
backside of tree panels at top, with lower straight
edge flush against platform, side slant edges slightly
offset back from edges and tabs, and attach securely.
FINAL ASSEMBLY
(Complete one end of tree assembly before
beginning second end.)
40. Working quickly, apply quick-grab glue to 
the low edges and behind  tabs where surfaces
 tree of tree panel and walls will touch, between 7 "tabs" at
bottom only of tree and floor panel, and . . .
 
. . . also between bracket strips and to backside of
vertical flanges, then . . .
. . . slot the bottom edge of center wall into space
between connector brackets while at the same time
inserting the "tabs" of tree panel bottom edge
to interlock with the floor panel "tabs". Adjust and
check until all are in place as described, then
hold and apply pressure until secure.
41. Apply same adhesive at low edges of tree
and side wall "curve" then wrap "tabs" into
position and secure.
42. Continue in the same manner to apply
adhesive to the low edges and also behind tabs
where surfaces will touch to the remainder of wall
and tree. Wrap it into position and apply pressure
to secure interlocking "tabs".
Repeat for the opposite round corner and side.
43. Repeat steps to position and attach second tree panel.
44. At front and back drawer walls, flex the top panel
flange back away from drawer grid to apply glue
to flange, then reposition flange behind window
opening, with perforation even with window edge.
Apply fingertip pressure all along by reaching into
top drawer openings row. TIP: it may be helpful
to use small binder clips into same position where
fingertips could reach to apply pressure.
45. Repeat similar process to flex shelves to apply
glue along front flange, then reposition with shelf
perforation even with bottom drawer opening edge,
and apply finger pressure to join securely in place.
Here is top shelf. Also repeat for middle and . . .
. . . bottom rows (on both front and back panels)
where finger opening will allow pressure to be
applied to backside of shelf flange.
FINISHING
46. Apply glue to the face surfaces of crest beam
connector flanges and to tree panel top tips, 
then position crest beam assembly along top space 
between drawer panel top edges,
with flanges tucked down behind panel edges until
perforations are even with panel edges.
Hold in place and apply pressure at beam ends to
secure in place. Also reach fingertips up through
windows to secure connector flanges in place.
47. If this has not already been done (see step 27),
apply quick grab adhesive to backside of accent
tree shape, then position so that slots fit over
tabs, and attach in place, on both tree faces.
48. Apply double-sided tape to backside of
finger holes cover, then insert it through bottom row
of windows, position to cover finger openings of
bottom shelf, and apply pressure to attach in place.
Repeat for opposite side bottom shelf.
49. Slide the numbered drawers into position
(this may be best accomplished by first tipping front
upward slightly to tuck back rim reinforcement 
under opening edge) and push fully in.
NOTE that the drawer depths were designed to be
slightly "proud" or not flush with front panel face to
assist with opening.
Drawers 1-12 are arranged on chest front,
with 13-24 arranged on back.
Here is the completed chest with front drawers array.
Add embellishments or decorations as desired,
such as this small ribbon bow and holly sprig.
