This puzzle uses twelve M2 screws with length 12mm. Be sure to get flat head screws! You can order stickers from Oliver Nagy's sticker shop here: http://oliverstickers.com/stickers-for-shapeways-puzzles/eitan-cher
If you do not want to dye the puzzle yourself, you can order in Black Strong & Flexible for a total of $119 by selecting that material from the materials list.
For now, I will not be offering assembled, dyed, and stickered copies of this puzzle as I simply do not have the time.
