Cover for Rear View Safety back up camera

[OldManAlaska]

I have a 1999 Tiffin Allegro Bus. The original Rear view camera was broken and not worth repairing when we purchases the RV a few years ago. We purchase a new Rear View Safety 4 camera system, ran new cables and a mobile mule. I have been pleased with the system with one notable problem. The old camera system had a weather shield surrounding the old rear camera, the shield was too weathered to carve a hole that would fit the new larger camera. This is an issue in rain, snow, dust and blowing debris.
I have been unable to locate an aftermarket shield of something I can make one.
I am hoping someone have a similar experience and found a solution. Thanks.

PICS? ....Check thingverse for 3D print files. You can make fiberglass items by carving stacked foam shape ,use gas or solvent to melt out foam maybe old one can be covered with glass/epoxy. Places do vacu-forming melts sheet of plastic over positive mold, maybe old one could work as well.
