I play with different educational manipulatives for a living. (Visit www.weirdrichard.com). Over the years I have built different holiday themed models using all sorts of toys. To celebrate the earth, this instructable will describe how to create a model of the recycling symbol using fischertechnik elements! Building the symbol might get youngsters thinking about a greener way of life!
The universal recycling symbol is a well-recognized image used to designate recyclable materials. It is usually composed of three chasing arrows that form an unending loop. I am modelling a recycling symbol used by Taiwan. This symbol uses negative space to create arrows pointing outward.
Wikipedia's entry on recycling symbols:
Note: The CAD looking images were generated by LDraw/MLCAD and a fischertechnik elements library.
Step 1: Gather Your Parts
You will need to gather your elements. The fischertechnik elements are available from a range of kits available from ebay, Craig's List, or fischertechnik retailers.
Elements can be purchased individually from www.fischertechnik.com.
