This is a simple little design to cover the hot shoe on a photo cameras, Canon, Sony, Fujifilm, Nikon, Olympus, Minolta and more.
Unfortunately I have no Leica I can't prove that it works.

This cover protects the hot shoe-connection against corrosion
Model created in real world size.

I hope you like it
Thank you!
