Guys remember that we do not have the tools to do it better.
Come on guys, give us a break. We are a bunch of hobbyists executing this challenging project.

Apart from the size it's great work. Given that you have to make it round, screwing into the camera housing's rear viewing port is a very good idea.
It's always better to use the tools at hand and make something that works than to never even try...
