If i were to design a discrete smoking pipe in the shape of an everyday item, would i be able to use your service. Thanks,
The only two "prohibited" items are weapons and items of sexual content. https://www.shapeways.com/support/faq Just be aware that none of them materials except ceramic are considered "food grade".
I think "Discrete" is the key word here.Lots of things you can smoke in a pipe. Could possibly be frowned on.
Given that 3D printing is both addictive and mind-boggling on its own (as well as a potential money drain), I think printing a bong would be kind of redundant.
