Rubik`s Dice Cube

NOTE! There is a first (not good) version of cube with 0.2 mm tolerance. Best version of cube is published on https://www.thingiverse.com/thing:6781983

This is a famous engineer Rubik puzzle cube. I'm designed this model myself in FreeCAD.

It has a next parts:
1 core
6 center "cubes"
8 corner "cubes"
12 edge "cubes"
6 pins for connect center parts to core.

There are some zip-files for your convenience - it has a whole plate of parts with supports (not made by slicer). Before assembling the cube, you need to remove the supports with a knife.

Instruction of assembly:
1. Connect each pin into center "cube" with a click sound. See that a hole in center cube has a groove and a pin has a skirt.
2. Insert a central cube with number 6 into the core with a click sound.
3. Put this part on a table and assembly all of cubes (4 edges and 4 corners) with number 6.
4. Insert another 4 central cubes (number 2, 3, 4, 5) into the core.
