3D Design - Stable structures

The brief for this challenge was to create an object that would hold a person off the ground using 10 pieces of cardboard and masking tape whilst having the ability to be flat-packed. 

I decided to use triangles as a basis for my structure as I felt like they are able to withstand a lot of pressure with their prism basis much like the circle that I used in the last challenge. I drew out brief sketches in my sketchbook before completing a final idea that would hopefully be able to lift my weight (see sketchbook).

I began by scoring the sheets into three portions longways with a Stanley knife, as going across the card would be weaker due to the ridges in its structure. I then cut the single sheet into a further three sections in the opposite direction of the scores. I proceeded by folding the sides up on the three sections and taping them in place to make three triangle prisms.

I secured these prisms together in the formation shown below, to make a sort-of large rhombus shape. I had to make four of these sturdy structures which I would then place on top of each other to make two hexagons to make up the two shoes. 

Above are the images showing how I constructed the shoes. This task was very difficult and at this point I was skeptical that these shoes would hold anyone up at all. The prisms were strong by themselves and my theory was that together they would be even stronger, however I feel like this concept wasn't the right way to go as I was afraid of even testing these shoes out on anyone. 

The finishing touch to these shoes was a single strap on each one that the wearer could slip their foot into before supposedly walking around. I think that if these shoes were made of another material that wasn't cardboard then there wouldn't have been a problem, however the brief said I would be working with cardboard and in the future I must consider this seriously before going ahead with designs. 

Below are final images of the shoes. I did test their strength by sitting on them, which was the safer option of standing on them how they are supposed to be worn as it was closer to the ground. They managed to hold my weight for about 30 seconds before collapsing in a pleasingly smooth flattening motion, so technically they were able to meet the brief of being 'flat-packed'!
