I am offering an updated version of this ring on my etsy store at https://www.etsy.com/listing/104226956/doctor-who-tardis-ring-3d-printed
Due to shapeway's pricing changes and messsing up their markup this item will no longer be sold through shapeways.
A smaller version of my TARDIS ring for smaller fingers (to save you material cost). US ring sizes 0-7 available.
TARDIS model modified from version created by user Gossamer on thingiverse: http://www.thingiverse.com/thing:13109
