GÑ! - Fidget Cube Remix

This is a remix of http://www.thingiverse.com/thing:1798009
I tried to make it more simply to print and mount.
What changes:
- Don't need to stop midprint. All parts printed normaly.
- Srcrew holes for M3. Screw directly to plastic. Don't need inserts.
- Changed printed ball bearing for common 16mm marble ball.
- Magnet ring in the previous design can be now a simple printed ring, a magnet ring or a 625ZZ bearing.
- 'Cam' changed to 2 momentary 'clik' buttons.
-Detailed mounting instructions.

IMPORTANT NOTE: For a good finish, you may need to sand and glue some parts during mounting. I don't mention this in the instructions but you must remember always when you mount a part.
