10. Strength of the project
Strengths:
-The shoe rack’s size makes it fit in every closet and
enable it to store a reasonable amount of shoes
-Aesthetically appealing, acceptable and efficient
-The reason we chose it is because it’s challenging
Weakness:
-It is very complex

11. Problem statement for fabrication phase
 Our goal was to have every pieces at the correct size and
fixed just as the CAD drawings

12. Assigned design
Our assigned part on CAD was the interior parts of the
shoe rack with dimension 20.50’’×14.25’’×17.75’’

13. Redesign result
 Issues:
a) Handle: a handle made of wood would be unstable
b) Dividers: putting dividers between wood planks may
not work if one of the plank isn’t perfectly straight
 Solutions:
a) We decided to buy a metal handle
b) We decided to replace wood planks by pegs

14. Fabrication summary
 Issues:
a) The side panel was inclined after we screwed it with
the top panel, which made the box not perfectly
straight
b) The initial location of some screws would make them
collide
 Solutions:
a) We unscrewed and fixed it with a hammer
b) We changed the location of the screws, making them
farther from each other
We had to fabricate the outer box

16. Final cost
Item Quantity Price
Wood 1 sheet $49.98
T-nut 2 $1.99
Bolt 2 $1.49
Shop supplies Screws and glue $3
Total $56.46

17. Final reflections
 We’re satisfied of the final assembly as it rotates just like
we wanted
 We’re surprised of the low cost ($100 less than our
budget)
 There were few mistakes for the inner part but it had no
impact on the final model
