NOTICE: some companies are offering illegitimate copies of the Curvy Copter. Only Meffert's and some other retailers (The HK Now Store and some Hong-Kong based retailers) offer legitimate Curvy Copters for which I will be paid a royalty. Please avoid buying from any other source. Any Curvy Copter which does not carry my signature and the Meffert's Challenge logo is illegitimate.
The Curvy Copter is my most popular puzzle yet. It is a variation on Adam G. Cowan's Helicopter Cube. By angling the cuts, the otherwise invisible centre pieces become visible and require to be in the correct orientation for the puzzle to be solved. Coincidently, the angled cuts also result in the beautiful pattern of curves on the puzzle.
The puzzle rotates very smoothly and is very stable, thanks to the V-Cube inspired mechanism. I built this puzzle in February 2010.
Please note that despite the appearance of Curvy Copter II, the name of this puzzle remains Curvy Copter, not Curvy Copter I.
This puzzle can be bought as a DIY kit from my puzzle shop. A DIY kit contains just the 3D printed pieces needed to build the puzzle, you will need to supply your own stickers and screws, springs and washers (usually M3 size). I no longer sell assembled puzzles directly.Click here to buy your own Curvy Copter puzzle kit from my shopBACK
