An Italian police officer had gotten fed up with trying to test and build PCBs (printed circuit boards), so he came up with a 3D printed device that can do all of the frustrating work for him. He designed the PCB Workstation, which features articulated arms for holding elements in place. No long does he need to be frustrated by the lack of ability to hold tiny pieces in exact locations on the circuit boards. He has made the design files available to download on Thingiverse.
