I feel it needs to be said that you should not attempt to build this unless you are quite advanced at puzzle solving and building. It is very difficult to solve, and the puzzle requires a lot of processing to get it working well. (sanding and filing to get all surfaces smooth, small alterations to interior pieces to avoid lockups)
I highly recommend you build one of my other puzzles if this is your first attempt at a printed puzzle.

Post-Printing
This puzzle will require a large effort to make the surfaces smooth after printing. It is especially important for this puzzle due to the number of pieces that make contact with each other. I use a file and sandpaper going up to 1500 grit on my own puzzles. (180,320,600,800,1000,1500)
How I Designed This
This puzzle was designed in Blender 3d. I will make a base file available soon, but I want to clean up a few things still before I make that public.
