Superstrings is a Turning Interlocking Cube (TIC) puzzle with only two pieces. You can assemble and disassemble the puzzle with the correct sequence o...f sliding and rotation moves. (Solution provided in the attached document.)
This updated version of the award-winning
Superstrings puzzle
has been made possible by
Aaron Siegel's
Puzzlecad
program. The included OpenSCAD file can be edited to change the size of the pieces, amount of chamfer on the edges, and degree of offset on the faces.
There are four STL files. You will need to print the following parts.
For the A piece:
1 x Superstrings_Base_A.stl
2 x Superstrings_Arm.stl
2 x Superstrings_End.stl
and for the B piece:
1 x Superstrings_Base_B.stl
2 x Superstrings_Arm.stl
2 x Superstrings_End.stl
Please pay attention to the recommended settings and the advice to lower your extrusion multiplier setting if your printer/filament combination shows even the slightest tendency to over-extrusion (small gaps in your top surfaces is much better than small bumps).
Print the base A set first in one colour and then print the base B set in a different colour.
Check out the video to see how the parts are assembled.
P.S. I discovered that the splitting happened when I increased the chamfer setting to 1 mm. I have now reset it to 0.5 mm when none of my test prints had the splitting problem.
Notes:
Use 4 perimeters to keep the shell nice and strong. This is needed for the friction-fit connectors which have zero tolerance and need to be hammered together.
