The 3D Tangram as envisioned by my grandfather William Perkins. This is an updated version of the original Featured thing 15754.Takes the 7 piece tangram and extends it into the third dimension by making it a pyramid. Can be used as a puzzle to recreate the pyramid, or new shapes can be made by reorganizing the 7 pieces.The new Sphinx Holder conveniently holds the Pyramid upside down so that you can see the tangram shapes. The Holder also has some tangram puzzles on the side for you to match with your 3D Tangram. You can get some interesting landscapes with the 3D Tangram.See en.wikipedia.org/wiki/Tangram for info on the Tangram. Printed on a Sells Mendel with 0.3mm layer height, 2 perimeters, and 10% infill. Some of the pieces have duplicates in the .stl file. It helps to print two objects at a time so that the tips of the pyramid have time to cool and stay sharp. Alternatively, you can slow your print way down.The TinkerCad link for the 3D Tangram is here: https://tinkercad.com/things/lOnxXJeZkjIThe TinkerCad link for the Sphinx Holder is here: https://tinkercad.com/things/2pfj7gDxqge-3d-tangram-pyramid-sphinx-holder
