I made some custom back caps for my Canon EF and EF-S lenses, so that grabbing the right one was easier in my dark lens bag. My complete set is for sale (very cheaply) on Cults3d! This is how I decorate them for high visibility.
Check out where to download the set here:

Don't see your lens listed? Send me a message, I will create it and update the cults3d listing :)
