3D printed bike flashlight mount

This is a hack that enables the use of any regular flashlight as a bike light. Made for CycleHack 2017 - Lisbon (https://cyclehacklisboa.tumblr.com/).

Barrier This Solves: Reuse regular flashlight's to improve bike safety.

Step 1: measure the flashlight's diameter and your bike handlebar

Step 2: edit the OpenScad file and generate the STL file

Step 3: call a friend with a 3d printer or go to the nearest Makerspace/Fablab

Step 4: with 4 zip ties firmly secure it to your bike!

Step 5: Ride you bike safely.

This is similar to https://www.thingiverse.com/thing:250899

I've clean the OpenScad code and now it supports various zip ties and dimensions. Use the OpenScad file for your hack.

Happy CycleHacking!
