esquisse two

For esquisse two, the brief was to create a four faced pyramid out of xanita board. the base dimensions at 100mm by 100mm and the centre of the pyramid at 100mm. the pyramid must be able to be locked in place through a locking system that requires our own design.

The first step I took was to work out the measurements of the four faces, as this was not specified. We knew that the base was 100mm by 100mm and that the centre height was at 100mm so I went about finding the dimensions by drawing up a simple diagram, using basic lines and angles I found the dimensions needed. See the drawings below.

I began to play with locking systems and how I plan to keep the pyramid shape, with the esquisse one dovetail locking system working successfully I decided to find a way to apply it to this model.

I found that the folds for the faces of the planes had to be cut at a certain angle to allow for the shape of the pyramid and for each face to meet equally at the centre. After much experimentation i found that the cut should be made on a 32 degree angle.

Because the dovetail locking system is designed to lock one side into place allowing it to be opened from the other side, it meant that each side was locked in once the side next to it was attached. This allowed for the entire model to consist of a strong solid shape.
