Icosahedric star

Make the inner segments with the straws cut in half. 13 cm approx. and the tips with the full straw of approximately 26 cm. All straws are 6mm in diameter.

Straws may need a dab of Bondex on their tips to stay in place. 

You need to print 12 pieces for the central icosahedron (Green part) and 20 pieces for the end of the tips (Red part).

No supports are necessary. They can be printed without infill but 8% is enough to remain completely solid.
