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
