This is the first time I hear of Precious Plastic. The community seems really positive, the site is awesome and professionally done (especially the map), the amount of content and already done tools is impressive.

The video and how-tos already give some ideas to produce (t-shape beams, geodesic dome connectors, wall sockets, bricks, carabiners...). I'd like to get a feel for limits and when it's not suitable to use. For example: how safe is it to have food in recycled plastic bowl, how much load can the t-beam hold, what's the melting point of brick, how much abuse the stool can take. Of course it depends on type of plastic used and probably pellet sizes and duration of extrusion. Can you give your opinion?
