Rubiks cube for FDM printers

Rubik's cube for FDM printers, it works fairly well and I've designed it to be as printable as possible, (Screw holes are triangles and go through the layers rather than between them as most core designs I've seen) When printing, you will need to make the core and centres fairly strong but the outer cubes can be made light. Simply use CA glue to stick the two core hemispheres together lining them up by the little mark, then drop a screw in after the glue has set to pin it all together. Put a screw through a washer and spring then through a centre piece and into the core for each of the six centre pieces. You can assemble and disassemble without removing the screws so its ok to glue the colour caps on once you have a cube shape.

Assembling may take some trial and error but start with a ring of edges around the core and work your way out with the final piece being an edge.
