Helicopter Plus(Twisty Puzzle)

thingiverse

So this is essentially the Curvycopter Plus on steroids but in a helicopter format. It doesn't require any external components; instead, I've added internal pieces that make all the difference. I haven't printed this model yet, but I have successfully printed a helicopter chop - basically, an aircraft cut in half - using the same design, and it handles remarkably well. I'm confident that this version will match its predecessor's performance. To assemble this model, you'll need 12 M3 screws and 12 springs. The pieces are labeled with a format of PieceType x Quantity.stl, making them easy to identify. If you decide to print it, please share an image so I can see how it turns out. You might also consider tweaking the core design to make it more compact or easier to print; feel free to modify and post your results here for everyone to enjoy. If you'd like to use a different type of screw, just let me know its dimensions and I'll do my best to redesign it for you!
