About this 3D model

It is a simple C-clip mechanism that holds battery powered round lights, like the "DOT-it" (no ad, just had this version lying around and needed a new light for the garage...) in place, so that you don't have to glue them somewhere and you can replace the battery without having to rip off any annoying glue... It shoud be good for any round battery spotlights with diameter around 67mm and thickness about 18mm, excluding the glass. But you can also scale it if something doesn't quite fit.
