Bicycle Light Rear Fender Mount 50mm, 20mm square

I needed a way to adapt my 20mm square rear bicycle light to a fender rack mount that had 50mm spacing. I remixed and melded two models together so that it would fit on my Ortlieb Quick Rack mount. 

Please note that you should print this model face up with “normal auto” support and in something that can handle being outside (like PETG)- this way the layer lines are orientated correctly for better strength. You will need to gently remove the support material, otherwise you'll risk breaking the spring tab. I was able to do it with a small screwdriver.
