As I am AFP (away from printer) for a few days, no new prints for a bit. But I want to point out a web site I just ran across.
Walter at thrinter.com has a lovely overview of many types and makes of filament, including his own (extensive) experience with many of them. It's a valuable resource for anyone curious about which filament to get for their printer.
It's also an interesting source of inspiration for what and how to design, and a good place to look if you're not sure what a 3D printer is good for. In the PLA and ABS sections in particular, he shows plenty of example prints, from the artistic to the immensely practical, often with design tricks I hadn't considered and that you rarely see in commercial products. Well worth a look.
