Yesterday's 3D design is today's actual thing! My 3D printed frame actually fits my little LED light.
The blue frame is what I printed. It took me 2 tries to get the settings right, on the first one, the corner of the quick release adapter didn't adhere and fell off.
Before it fell off a table and broke, the little LED panel light required that tree of adapters seen in the lower left corner, to make it go in a quick release tripod clamp. The new frame does away with all that.
