I was playing around with TopMod again to try and create some more hollow cubelets for puzzle pieces. I came up with one nice addition, the
TwinCurlCornerCross which replaces the central square of the CurlyCornerCube (seen in the Quaturnery puzzle) with a central cross. I have used this basic unit to create a version of Stewart Coffin's classic
Convolution Puzzle.
Then I went a bit further in TopMod and started playing with additional features on the inside of the cube's skin. After a while, I realised that I had accidentally created a cube where the corners were completely disconnected from the faces, leaving a shape somewhat reminiscent of Virtox's
Gyroid Bones.
I have ordered a test print of a 2cm
Complex cube in metal and a WSF version of the
Seldom Seen Cube made from 1cm complex cubes. One interesting feature of this puzzle (if it works) will be that corners of adjacent cubes should fuse and the face circles should also fuse, but each puzzle piece should consist of two independently moving parts. If this works, the central pins of one piece could snag in the central holes of another, adding a completely new layer of complexity to solving the puzzle. I'm really curious to see if this works!
I'm not completely sure that either of these will be successful (or even possible) but Shapeways never stop surprising me with the quality of their service.
