3-5-7 Game

thingiverse

This game was something I remembered playing during grade school, but hadn't encountered since then. The objective of this game is forcing your opponent into flipping their final piece. When making a move, you can flip any number of pieces within one row that suits you best. Although it's technically possible to win every time, achieving this would involve questionable sportsmanship. The manufacturing process requires two STL files - the main board and fifteen separate pieces. The primary game board features built-in voids on its underside for minimizing material use, along with arch-shaped cavities designed for smooth printing without requiring additional supports. Once printed, the components can easily fit together. These design files were initially created in VectorWorks before being exported as STL formats compatible with 3D printing. My Printrbot Simple Metal successfully produced the main board within a 3-hour window and the fifteen pieces under an hour.
