Toothpick Fractal Pyramid

A fidgety pyramid made by stacking the iterations of the toothpick fractal on top of each other. The model is inspired by a video on Numberphile that explains the toothpick fractal which I highly recommend watching. Stacking the iterations on top of each other made the Sierpiński triangle show up when looking on the model from the side, which was a nice surprise I didn't know about until I designed and printed it :)
