The friendly people from the German Reprap Foundation (short: grrf) – contributed half a kilo of tranparent PLA, which is a plastic material made out of starchy plants. We are going to use this PLA Filment on our Prusa Mendel 3D Printer in the OTELO (the Open Technology Labaratory), to produce the light guides of the VU-Meter, On-Air and PowerLED for the OggStreamer.
Thank you Jan & Florian @ grrf.de
