Rubik's 3x3x3 skeleton
this is a Rubik's cube hollow with dovetail mechanics.
How to print this?
I have used ABS, acetone vaporized. I want to say, this object is ABS only. I have made some test pieces in igus I150 filament. It would work but ABS is better in this case. This object needs a lot of time to clean the printed parts.
Print calibration cube. Tolerance of outside and inside has to be better than +/- 0.05mm. If not, adjust your slicing software [xy-calibration parameter]. If your slicer doesn't provide, use annother slicer (slic3r and repsnapper has)
If your calibration cube is ok, then use the attached files with '03'. This means it is a 0.3mm gap in the dovetail connection. If your calibration cube is bigger, use the 04-files, if smaller use the 02-files. This is untested.
Slice it, use support material.
Print test pieces: one of each, then test if fit.
To clean the dovetail tracks from support, use a tool as seen in photo. It is a piece of sheetmetal, bended and grinded. Sandpaper it. If PLA: sandpaper it very carefully.
acetone-vaporize it (ABS only).
- I don't know what's better: colorize first then assemble, or assemble first then colorize. Use vaseline or annother grease at assembly (important).
