Saddle mount for "Smart LED / Planet Bike" lights

UPDATE, improved version here: http://www.thingiverse.com/thing:195179 I've been using Smart LED / Planet Bike lights for years as they are cheap bright and reliable. Unfortunately the seatpost mount doesn't look that great so I looked for a more minimalistic mount. This thing just clips on standard saddle rails and does it's job pretty well http://www.amazon.com/Planet-Bike-Blinky-3-Led-Bicycle/dp/B000RYAKHC/ref=sr_1_4?ie=UTF8&qid=1369331552&sr=8-4&keywords=led+bike+lights
