This is an oddly specific bracket I needed for my Amazon Electight puck-shaped motion sensitive rechargeable LED lights.  They include a nail hole that allows them to attach to a wall or the inside of a cabinet.  It is not designed to be used upside down from a ceiling, so I don't recommend doing that.  This is an alternative to the magnet / nickel plate option the base model included to mount it.  Using my mounting bracket allows the light to still be removed to recharge, but makes it more bump resistant.  

I print it with PLA and no supports.  I used the default slicer settings and have no problems with them.  This means we need an infill of 15% and three outer walls.

I designed this in TinkerCAD Codeblocks, so if needed, I can easily generate a slight variation on this model.  Within Codeblocks, this model is entirely parameterized.
