Tactile Food Chain

In order to use the device it is necessary to employ a galvanized steel sheet, Neodimio magnets (2 for each object board) and rubber strings. The rubber strings must be tied at the start pin and ending pin. The start pin means "this animal/plant is food for..." and the ending pin means "this animal/plant eats/consumes...". The magnets have to be glued underneath the objects boards. The silhouettes can be either printed at the same time of the bases in printers with two extruders or you can print the silhouette in separate and glue it on the base.
