Lowrance Sonar Screen Guard (Rain & Sun cover)

thingiverse

I'm looking for a screen guard that fits my Lowrance Elite-4X sonar perfectly, and it's a great bonus if it can also protect the device from harsh sun and rain conditions. I need this screen guard to have two bars at the top and be mounted on the back, and it should come with its own cover to keep everything in one place. To assemble it, I'll need four machine screws (M3 size) and four nuts to match, all of which are a standard M3 size.
