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:
You need 4 M3x12mm screws and 4 springs. You can buy the springs from here:

The screws for this puzzle I found laying around in my house. The screws in the link above are too long, so you need to find shorter screws. The ones I used were 12mm long.
Stickers can be cut from the template, or you can use helicopter cube stickers.
