ROFI front body panel for SR04 ultrasonic sensor (parametric scad)

I recently built a ROFI but since I bought the cheapo SR04 rather than a Parallax Ping sensor, it didn't fit in the front body panel holes. So I took the original file, patched the holes in Open Scad and cut new ones. I made the scad file parametric while I was at it just in case someone else wants to change it for some other cheapo sensor they might find online. I didn't add any good way to anchor the sensor to the body panel but the original file didn't have any way to do it either.
