Hexagonal chainmail. This project is intended to showcase the pattern making tools of 123D Design, including both circular and rectangular paths. Simple as it is, it shows the value and fun of 3D design and printing. The 123D file is included so you could tweak it as you please.
Feel free to scale it to about 80% if it is too big from a 140mm^2 bed.
Carefully remove the whole piece.
