Flashlight stem mount for bike

thingiverse

Here's a versatile bike stem mount for your flashlight. It's designed to fit stems with diameters of roughly 1.25" and lights with diameters of about 1". To assemble this mount, you'll need four #8 flat head machine screws that are 3/4" long, along with their corresponding nuts. You'll also require one #10 screw and nut for the quick release mechanism - I used an old GoPro knob from my parts collection. You can position your flashlight either under or above the stem, depending on your preference. However, keep in mind that this mount won't work as well if your stem is angled upwards. The STL units are based on inches.
