Chevy Stereo Support

I have a 96' Chevy truck and the radio went out. My wife, being the loving wife she is, thought that she would buy my another one to replace it. She knew I wanted a bluetooth for my next radio, so she asked around and found one online at walmart and had everything sent, except for the insert needed.
When I saw what she had done for me I was excited to put in the new radio, but ran into a little snag. The old radio was a dual and now I had a single. I just happened to need to go to the store and noticed how expensive the inserts were. $30!! Really?!
But I have a 3d printer, I will make my own I thought and I did.

This support/cover is simple comes in two pieces or in four(smaller printers).
