This model has been replaced with a more detailed model that is too delicate to be sold on Shapeways. But you can buy the files upload them to Shapeways and have Shapeways print them for you using the “print anyway” option. Just go to my website for details.

This model used to also be available in frosted ultra detail, but after many succesful prints shapeways decided to stop printing it, so now it is available only in extreme detail.
