BAT Hat Ping Mount

I've been working on a "BAT Hat" for about a year now as a side project: Blind Assistance Technology. It's a hat that can provide distance feedback based on Ping sensors. Originaly I had the sensors hooked up to vibraing motors for a haptic feedback system, but the latest version plays audio. All through Arduino\Adafruit Wave Shield.

I needed a way to mount the ping sensors to my hat. Originaly I'd just used some Shapelock to for some simple brackets, but they weren't adjustable, and looked like play-dough ;) Plus, I didn't have a Makerbot back then. The top part of the mount I derived from what UechiMike had developed (thing #19256), but the bottom was modeled custom in Maya: It's designed to slip around the brim of a hat, and you can drive a screw through the bottom to hold it in place. Another small nut\bolt hold the top\bottom brackets together.
