Important! Because this is a sliding puzzle, please don't expect to justassemble it and have it work. You will most likely have to do some sandingto get it to work smoothly.

It is intentionally designed to be a bit tight due to the nature of 3D printsand how layer lines will wear over time. I'd rather it be rougher at first andsmooth later than perfect at first and too loose after it is worn in.

Sanding speeds this process by smoothing the ridges. So if your cube feelsvery rough after assembly, you can either sand it some more, or just giveit time and use to get it to become smoother. When sanding, payparticular attention to faces that rested on supports and the slidingcontact faces of the inner "sphere".

The puzzle is also slightly larger than a standard cube so that it can printsuccessfully on a wider range of printers. If your printer is capable, youcould probably scale it down to 66% and use M2 screws instead of M3.

Required parts:

6x M3x20 screwsSandpaper or small filesPlastic-safe lubricant (optional)

Print:

**General Notes:**

You may wish to print the "core" part on these plates by itself as ithas a small footprint and might detach, ruining the rest of the plate.The "center" part is designed to be printed without any support whensliced at 0.2mm layers. There will be a single-layer bridge blockingthe screw hole when done. Just cut it out with a sharp hobby knife ora drill bit.The corner pieces _can_ , in theory, be printed without support, byplacing them with the small flat area (on the triangular protrusion)face down. However, this is not recommended unless you have verygood bed adhesion (and use a brim!). If the part wobbles then youwill have difficulty getting the end result to move smoothly.The snap-in inserts are compatible with the MMU printed parts. Soyou can go for a two-tone effect or change colours later if you want.The core is deliberately very tight on the screws. This is so thatturning the faces does not loosen the screws! Do _not_ tap or threadthe core unless you are prepared to use superglue or loc-tite to keepthe screws from coming out.

**Non-MMU:** Print all parts in Cube_Core.3mf. Print 6 sets of "Insert"plates in your 6 desired colours. **MMU:** Use the Cube_MM.3mf plate.You have some choices to make, because the MMU can only handle 5filaments at once. You can either:

Opt to print one face with the same colour as the cube internalsPrint the internals in a different colour than the faces.

_Note: The parts are **not** placed optimally in the MMU plate. They areplaced for easier visual reference as to where that part fits in the cube!Look at the non-MMU plate for reference in regards to supports - but atminimum, flip the center pieces (with screw holes) square-face down andselect "support from build plate only"_ For option 1, print the plate once asis, after setting your desired filament colours. Observe the previous noteabout printing the core separately. Your purge block will be rather large, soif you have a suitable item you can use as a wipe model, use it! Then,remove the 8 outer-most parts and core, leaving just the inner 9components. You will need to reassign colours, i.e. red becomes the sixthcolour, and two of the opposite sides' colours will swap places (e.g. blueand green). Print the remaining bottom pieces. For option 2: Remove therearmost six parts (the ones with white faces) on the exterior. I suggestdrawing or sketching out the colour combinations and parts you will needfor this as it is difficult to describe with words. Then tick them off as youprint, swap one filament to a new colour, and print the next batch.

Assembly:

Sand the appropriate faces as in the general notes. Cut out the bridging covering the screw hole in the center pieces. Screw five of these six pieces to the core. Do not tighten all the way!They should still spin freely, but not have very much play parallel tothe screw. Start slotting in the parts. (You can optionally add some plastic-safelubricant to the faces of the inner sphere to let your cube slidebetter.) bottom edge pieces first, bottom corners, then center edges,and finally the top layer. Install the top center piece. If you're printing the non-MMU variant, snap in your coloured insertsnow. You might need to trim the center ones a little to sit flush,depending on your printer's tolerances, and owing to the supports ithas. They should be a tight snap fit by themselves, but you can gluethem if they start falling out or you accidentally break the lip duringassembly.

Troubleshooting:

If your cube is too tight, try backing off the screws a small amount.If it feels rough, either sand some more or break it in as describedpreviously. If it is too loose or pieces pop out when you try to turn it, tighten thescrews. If it catches when turning, inspect (and sand down) the faces thatwere sliding - look for ooze, sharp corners or wipe marks you mighthave missed
