This thing has moved to Youmagine https://www.youmagine.com/users/jensa so I don't also get sued by Stratasys...

At our Oslo hackerspace (Bitraf.no) we needed something to hold PCBs while they were in the PCB tank, so I made this "general purpose PCB holder"

Keep in mind that PLA melts at 60 degrees. I had to use ABS or it would melt when used in the heated PCB tank ( like this one http://www.instructables.com/id/Vertical-Etching-Tank-for-DIY-PCB-etching/ )
