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.

Blog post here giving more info on the hat, file downloads, etc:

I needed a way to mount the ping sensors to my hat.
