edit: 11-27-2016 Added Template file for stickers.
edit 2-2-2017 Added revised center pieces. The original ones are now labled as "old" and are no longer needed. The new centers provide for more spring motion making the puzzle more stable.
This is a 57mm puzzle cylinder. You will need to provide your own core and screws/springs from another cube. I recommend using a YJ Guanlong core, as these can be found for $3-4 and this has been designed with that core.
Surfaces will need to be sanded smooth to allow best operation of the cube, and to allow the stickers to adhere properly to the sides. It is fun to solve even without stickers as well.
The number at the end of each piece is how many you will need of that piece.
I printed mine at standard since I do extensive sanding to smooth everything anyways. The curved surfaces may benefit from a higher resolution though, and it may save some sanding work in the end.
I recommend sanding all pieces thoroughly for best performance. I use 180, 320,800,1000,1500 grit sandpaper for a smooth polished finish.
This puzzle has been designed completely with open source software. I used Blender 3D for all design elements.
