Hearing Funnel

The seam seems is nice and tight after the last set of revisions. The bracket interfaces with the helmet but needs to be beefed up a bit, and I think I need to add a slot to the end of the top piece to help keep it more square,

The print quality on the first one of these revisions was a little bad on the attachment for the strap, but it still works nicely and holds in place quite well.

I am still able to hear the sounds to the front and side and now can direct my hearing behind me. There are still a number of improvements that could be made but I could make but I feel that as a warm up I was able to solve a good number of problems and refine my design quite a bit.
