Rubik`s Dice Cube v2

This is a famous engineer Rubik puzzle cube. I'm designed this model myself in FreeCAD. As opposed to previous version with tolerance 0.2 mm this cube has a zero tolerance between parts.

It has a next parts:
1 core
6 center "cubes"
8 corner "cubes"
12 edge "cubes"
6 pins for connect center parts to core
189 small dots in different colour.

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:

0. Insert small dots into holes in each cube with glue (Dichloromethane for example).
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.
