Hype bluetooth headset around-ear adapter cups

On-ear headsets may be very cost effective, but are very uncomfortable after about one hour of wearing them. I bought this $20 dollar Hype set and then designed some ear cup adapters so that I could wear them indefinitely. Go to Lowe's (or whatever hardware store) and plunk another 4 bucks on some foam backer rod and, voila... you just saved yourself a bundle of money by printing your own over-ear bluetooth headset! Nice.

Here's the assembly vid:
