End Cap for SMD Component Magazines

Designed for robin7331's SMD magazines on his standard rail.

I wanted to have a nice end cap to cover the one open magazine at the end of a rail, to keep everything neat and tidy. This cover is based off the exact profile of the magazine, but 2.4mm thick. I made the compliant spring wider to accommodate for the fact that this is so thin. I also changed the handle so it does not get accidentally pressed when I am removing an adjacent magazine (sausage fingers). Easy print nothing to worry about.
