Rubik's Cube Remixed

thingiverse

I haven't had much luck painting PLA and stickers don't seem to last long, so I decided to modify Ekobots-Rubik's Cube. I indented each outward-facing face slightly then printed a bunch of tiles to fit into the indents. The core is still the original file, so I didn't upload it. This isn't a "Speed" cube by any means but it is fully functional. I printed everything in PLA and used six M3x25 with six M3 washers. UPDATE: I was having trouble with screws backing out of the core after several twists on my original cube, so I made another modification. I modified the core itself with 3mm nut insets. The nuts were very tight already, but for added assurance, I glued them in place to prevent them from moving. I also use white lithium grease to make it twist even smoother. UPDATE #2: I was still having trouble keeping screws from backing out while twisting the cube, so I redesigned the core from scratch using Fusion 360. In order to make it easier to print, I cut the core in half, added fillets and made it so that three-millimeter square nuts can be used (this way they won't twist loose). Also, I printed the new core in PETG to give it more strength. Print two pieces of the RC Core v2 and then, when gluing them together, make sure that the holes line up with the cutouts. If aligned properly, you will have channels for all six square nuts. I also printed the new core without supports using Slic3r and it only required minimal cleanup on some overhangs at fifty percent infill with point two layers. Also used a drill bit and cleaned up the screw channels by hand. Be careful not to over-tighten the screws. I did, and I broke one of the corner pieces and side pieces (which I promptly reprinted).
