This is a fun and simple project to make. It consists of 12 pieces that are all the same size. The pieces shown are made from wood and are glued together to make 3 assemblies. Getting it apart or putting it together is the challenge. As always, there is a trick. I've provided 3 STL files - different build options Option 1: Print 12 single pieces and glue them together as shown in the instructables link. Option 2: Print 6 of the two piece combined sections and clue together as shown. 3rd Option: Print the completed assembly. You will need to print 3 of these Build Instructions: https://www.instructables.com/id/Hexagon-Puzzle/ Solution: https://youtu.be/QUmHdIprCl0
