2x2 Turing Sphere

This is the 2x2 Turing Sphere, a twistypuzzle wich is a ghosted and bumped 2x2 sphere. I named it after the great british mathematician and codebraker Alan Turing, who broke the Enigma-Code in WW2.

You will need a 24mm 2x2 Keychain Cube as the core, because these are extensions. You can use this one here: http://www.cubezz.com/Buy-4231-XM+2x2+24mm+Mini+Magic+Cube+Keychain+Black.html

You have to sand the pieces a bit, so they stick better on the 2x2.
I hope you'll enjoy this puzzle, if you print it, send me pictures of it per instagram direct message, my username is "cubic.space".
