Flashlight support to mount 27Ø tactical light to your bike.
Parts will be stiffer if printed in the direction shown in the screenshot.
I also recommand to use PETG rather than PLA which would decay faster with outdoor condition.

I printed mine on Ender 3 Pro
eSun black PETG
0,2mm layers
3 walls on every sides
20% filling

Recycle the rubber from old inner tube to make a grip between the support and the handlebar, and to make excellent rubber band to fix your flashlight.
