Sensor holder - with Fischertechnik connectors

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 ]
