Master Chief Rubik's Cube

thingiverse

CSG intersection of a Rubik's cube model with a Master Chief's helmet. https://youtu.be/Lwcgd74nh6g ## Printing Print with supports. The models should be aligned so that the inner cube pieces are faced upwards to give them the best mechanical properties. This, of course, means we compromise the Master Chief's details being scarred by the supports. There will be 26 cube pieces and 1 core. Files are named using a HaloHelmet_[PCN][PCN][PCN] convention, where each PCN group will list if the piece is a positive, center, or negative piece of the cube on the XYZ axis. ## Assembly * 6 M3x25 Socket screws will be required to connect the face pieces to the core. This thing does **NOT** use washers for the face pieces. See the previous assembly video for the Ekobots Rubik's Cube, https://www.youtube.com/watch?v=XCINIB-83qQ This assembly will be FAR more complicated and tedious (than the original Ekobots) as you cannot rest the cube on the table during assembly. I don't know what to say except *god speed*. After initial assembly, rotating the cube repeatedly with force is recommended to smooth out the insides and remove snags and burrs. See included color-coded alignment image for assistance. ## Caveats Small pinching risks - nothing I would categorize as hazardous, though. If the cube is scrambled or partially rotated, some cube pieces will expose sharp edges. ## Source File Blend source file included. * The `Controls` object has some object Custom Properties to drive various tolerance parameters. * Each exportable piece will have an `ExportSide` property, which allows the Python script to automate exporting all relevant pieces to STL. The STLs will not be correctly oriented. * View the model in `Material Preview` mode to see material colors. Each piece will have its RGB color mapped to its XYZ spot in the cube.
