Rubik's 3x3x3 O-type (1) Square-3

thingiverse

Function is like the Rubik's cube I've published here.\nI designed a test of the 2D subsystem of OpenSCAD, and the result is this cube.\nSlicing without XY size compensation, I created a big gap between the moving parts.\n(0.3mm to each side equals a 0.6mm gap in the model.)\nPrint the number as written in the filename, regardless of PLA or ABS material choice.\nRemove all blobs and irregularities carefully.\nGlue the core parts together, stabilizing with pieces of 3mm ABS filament.\nFlat sides to the outside, check if it works smoothly before applying glue.\nFull assembly requires a M3 screw and a self-locking nut.\nPlace a washer between the two rotating core elements.\nI printed in PLA white initially, but that was not a good idea; it becomes dirty quickly.\nPrinting in color and ABS would be better options if possible.\nThe SCAD file generates only full cubes, no single parts.\nI do not recommend print-in-place due to non-smooth surfaces inside.\nSome parts must be rotated upside-down for printing.\nIf needed, import all into your slicer and select the split function (RepetierHost, Slic3r, RepSnapper provide this option).\nThe SCAD file allows adjusting cubie size, inner diameter, roundness of edges, and gap distance freely.\nEdit 2016-03-01 update: please use the actualized files.\nTwin projects: https://www.thingiverse.com/thing:3098632, https://www.thingiverse.com/thing:1967151, https://www.thingiverse.com/thing:3072245
