Canon5diii has a sports injury

New
Camera ,maybe 3 weeks old, lost its ring
Dial thingy in the top while at a rugby tournament never to be seen again . Made it susceptible to dust, rain and steam I suspect so sideline physio was applied to keep it
In the game ..good Bit strapping tape and plastic bags did the trick . Not happy with canon as had old camera for years and nothing fell off it ever.
