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. Note, that sum of dice number on opposite sides is 7 (1:6, 2:5, 3:4).
5. Put 4 edge cubes at a middle plane in according order.
6. Put 4 edge and 4 corner cubes with number 1.
7. Insert a central cube with number 1 into the core with a click sound.

For the best result, it is necessary to lubricate the internal rubbing parts with Teflon grease. You can also apply acrylic paint to the inner points using a medical syringe.

Note, that all parts of this model has a tolerance of 0.2 mm. It was my mistake, sorry! I'll plane redesign this model with zero tolerance.
