About this 3D model
A case for the HC-SRO4 sensor. Based on http://www.thingiverse.com/thing:24858 but with additional Fischertechnik connectors. Measure careful before printing. My HC-SRO4 board was slightly wider, so I had to widen the two holes to the sides. [Update: "sensorholder_fischertechnik_wider.stl" is a mod to adjust the holes a bit for my HC-SRO4 ]
