When I originally built K-9 I didn't have my 3d printer. Now that I do I figured it's time to upgrade a couple of parts. The first part I knew I wanted to improve were the buttons surrounds. Normally K-9 builders spend a lot of money to get the proper surrounds for the buttons on K-9's back. I was using bits of leftover black foam.

Here you can see the before and after.
