gyroscopic keyring 11

Six rings rotating freely in any direction to form a cool keychain.
One year later, an improved version of my " gyroscopic keyring 2 " at http://www.thingiverse.com/thing:644217
The file "portagiro special " is a simplified model, as requested by a maker.
Have a look at other gyro keychains:
