Bike flashlight mount

This is my take on a flashlight mount for my bike. I wanted something that has only one screw and when I get the light off my bike, the holder would come off also. I don't like carrying unnecessary empty holders.

I changed colors mid print by eye using the pause button in Repetier software.

I designed the thing using Autocad Fusion360.

My bike handlebars are 31.8mm diameter and my flashlight has 24mm.
My flashlight is a Convoy S6 with the most powerful LED from the options FastTech.com
