At Michigan Technological University, the smarties are shredding up those plastic milk jugs and feeding the scraps to the 3D printer--to emerge as a cell phone case or a safety razor.
The website Thingiverse.com has thousands of open source instructions for the neato-torpedo printers, which are coming down in price to as little as $500. You can even make parts for the printer on the printer--thus saving that cost.
The big cost is the filament--the plastic that is laid down in layers. So they made a device that turns the jugs into filament--again, check out Thingiverse.com.
Milk jug filament can be harder to work with but the price is right.
Twenty jugs makes about a kilo of filament--at $50 retail, this could be a little moneymaker for people in poor countries, too.
As we all make our own gadgets!
Two articles: March issue of Rapid Prototyping: Distributed Recycling of Waste Polymer into RepRap Feedstock by Christian Baechler and Matthew DeVuono. And Proceedings of the Materials Research Society--upcoming: Distributed Recycling of Post-Consumer Plastic Waste in Rural Areas, by Jerry Anzalone and students Megan Kreiger, Meredith Mulder, and Alexandra Glover.

If this is for some stupid black market pill, you are not being very creative..
