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

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
