First Useful Part

I've had a 3d printer for a while, and printed a few downloaded parts, but I've reached a milestone and printed my first part that I designed myself. It's a quick-release mount for an action camera on my bike.

I've had the cam for a few months, and used it on a helmet mount. I found the helmet mount to be a bit cumbersome and insecure, also I felt like an idiot with a camera on my head. I thought it would be better and less conspicuous on my bike, so I'd been meaning to work up a bike mount. Anyways, a few close calls and one incident in which someone drove their car full beans through my group ride (nobody was hit, thank the gods), and I finally got around to working something up.
