While tinkering around I was trying to come up with a way to make the battery options on the Fly lens 85 better/ easyer (size of different mah lipos differs) I found this plate on makers world. Its what I was looking for. I had to tweak a couple things to make it work with my frame and it is awesome. obviously you can print this in any color and a few different style filaments to your liking but I'm very happy with the ability to drop in many different style milliamp batteries and not have to worry about it not fitting!
