Files for printing paper connectors Connectors for tetrahedral double paille type to realize a Sierpinski fractal The opensad file is customizable in Customizer . The connectors have been created to realize the 5 solids of plato The connectors for the other solids are available. For cube : https://www.thingiverse.com/thing:3156338 For tetraedre : https://www.thingiverse.com/thing:3159099 For octaedre : https://www.thingiverse.com/thing:3159071 For dodecaedre : For isoaedre : Example : Realization of a 5 iteration fractal with Connectors for paille BMVR in Nice as part of the science festival 2018. Unice ( LJad ) - LP eucalyptus Mathematics exercise on sequences : Make calculations of successive iterations and estimate the number of connectors needed. We start from a tetrahedron of 10 cm side length made of paper. *To make an iteration in paille it takes 4 connectors, 6 pailles and 4 tetraèdres in paper *For the second iteration it takes .... And for the fifth iterations ..... We can do the same thing for length, surface and volume occupied by small tetraèdres. How does this evolve with respect to the size of the large tetrahedron . Strange, is not it ?
