60mm Camera Lens Cap

I have a 1960 canon RM and I've lost it's lens cap so I've decided to make one of my own.

This is a first model I made with Sketchup it works pretty good but I'm working to make it better using Fusion 360, a second version will be available soon.

EDIT: A second version has replaced the old one, I've made this one with fusion 360 and this allow me to make it compatible with other lenses very easily so if you need another diameter lease cap just contact me with the inside and outside diameter of your lens.
