Coronation Cube

This brain teaser is my entry for the prestigious 2014 IPP Puzzle Design Competition hosted by John Rausch at http://www.johnrausch.com/Designteam/Puzzleofthemontharchive.htm. It's a clever interlocking 5x5x5 cube that can be printed with minimal support, requiring only a small tab on one piece to be held in place. To print this puzzle, use a Mendel90 printer with the following settings: Rafts off, Supports enabled for the short tab on the ring piece, Resolution at 0.2 mm, and Infill set to 25%. Once printed, assemble the pieces carefully, paying close attention to the rotations required to solve it. I've included a solution document for those who need help, but feel free to challenge yourself first if you're up for the task. This puzzle was designed using Live Cubes, then refined in Burr Tools, where the STL files were exported with specific parameters: cube size 10 mm, bevel 1 mm, and offset 0.07 mm.
