To order, buy it from my Shapeways shop, and then be sure to send an email to eitanspuzzleshop @ gmail . com (remove the spaces) with your order number and which type you ordered, since I have to intervene and send them the correct files.
You can get stickers through Dr. Sticker (a really good source for custom puzzle stickers) for $6.70 for one puzzle, and $4.00 for every additional puzzle. Just email him at dr-sticker @ gmail . com (remove the spaces, but not the "-" dash) and tell him what colors you want on which faces. Be sure to tell him which type of Twisted Cube you bought, so he can send you the right stickers!
