First 3D printed bike project

My first home-made bike part on the 3D printer- a rear light mount for my Surly Big Dummy. When I have the baby seat mounted on the back of the bike, my rear flasher is blocked. That's obviously not safe- so I wanted to make a mount that was super solid, wouldn't be blocked by the baby seat, and wouldn't get in the way of any of the bike's cargo capabilities.

I designed the parts using Solidworks 2012, and printed them on my rep rap Mendelmax 1.5.
