Description
Sixes and Sevens is a series of 3D Symmetry Puzzles that I designed myself. Each puzzle consists of a 6-unit piece and a 7-unit piece, your challenge is to make symmetric shape out of these two.
By replacing 1 piece from Six Seven 1, we got Six Seven 2. There are 2 solutions, can you find them all?
The pieces in the photos are made using Lego-like (actually LiveCube-like) bricks, which looks good but is a pain in ass to print. The actual 3D model is made by OpenSCAD+Puzzlecad with standard burr-piece look instead. One of the pieces need support to print, which is fine in this case - Symmetry puzzles are friendly in dimentional accuracy compared to other mechnical puzzles.
