This is quite a tricky one. To achieve the final product, i had to do some experiments three times. The first one was done in class (workshop) and it was only a tryout to know the correct measurements to do the five sided pyramid. Then on the second attempt, i tried to find the best locking method. i failed, because it could not hold the pyramid strong enough if it is just one slot used. Finally on the final attempt, i succeeded by having the slots on each triangles, to hold it firmly and strongly. Below are some photos showing the progress.
