Quick release bike light
by paultbeck, published
This is a handle bar mount for a quick-release attached bike light. (Mine is a light & motion light that has a particular mount)
Modify the quick release insert for whatever you have. I did this in openscad.
You can use the instructions on the thing that this is derived from to put together the quick release mechanism: http://www.thingiverse.com/thing:13184
