Helicopter 2x2 Twisty Puzzle V2

V2 of My fully functional helicopter 2x2 puzzle. It turns much better and is more robust than v1. I changed the inner 2x2 mechanism and modified the helicopter cube mechanism to turn better.

This puzzle combines the moves of a helicopter cube and a 2x2. The edges can turn 180 degrees and jumble, while the faces can turn in increments of 90 degrees.

To make this puzzle, print each part by the number indicated on the filename:

* 7 2x2 Corner
* 1 2x2 Alignment
* 3 2x2 Center
* 9 2x2 Ed
