Stealth Rear Bike Light Mount. Cateye Orb Light

With an aero seat post it can be a bit tricky to mount a rear light. And they aren't aero, are they? This print mounts a Cateye Orb rear light to the seat rails (9 x 7mm rails, standard spacing), where it's a lot less visible when turned off (but works perfectly well when turned on) You just need to remove the rubber strap from the light and supply an M4 screw and nut.
