20130716 - I've temporarily made this unavailable as I've discovered while the slices are 0.8mm, the connecting line is slightly too thin! (this model was uploaded a long time ago before thickness checks were finalised) I'll have to look into this further.. my sincere apologies if you have purchased one and had shapeways told you it cannot be printed!
The '8cm revised whale' has been modified and should be printable without problems.
