Bike light holder

Want to increase your bike lights visibility?  Put it higher!  Got a drop-post seat where you can't mount a light?  Put it right under the seat!  These were my considerations when I designed this bike light holder.  Lots of 'rubber band' mounted LED's out there.  This works for any of them.  Use high resolution with raft and in 1-1/2 hours it printed on my Makerbot.  One important point is that you need to wrap sandpaper (fine or med is ok) around the threads and pin the threads.  The slight flash will wear a bit and you'll get a great threaded part that is nice and tight, so it doesn't 'unscrew' when your thrashing around.
