I needed more space behind a commercially available 180mm (7 inch) LED light fixture to accommodate older wiring and mounting hardware. This surround along with the accompanying spacer granted 24mm (almost 1 inch) additional room without making the light too bulky in appearance. In the old building I am working in it protrudes far less than the original fixture did.
The opening in the surround is 180mm (7 inches) in diameter with a slight bit of extra tolerance. The total depth of the surround is 40mm. The diameter of the spacer is between about 100 and 120mm (roughly 4 to 4.5 inches) which will allows it to easily attach the back plate of my new LED fixture to the old-work box and mounting hardware where I am working. The total height of the spacer is 24mm. Both the surround and the spacer could be resized on the Z axis after you lay them flat to make taller or shorter prints.
NO SUPPORTS: I printed the spacer in two pieces by using the cut utility and adding clip connectors in Prusa Slicer. Flip both pieces onto the ring surface and no supports will be needed. You could print it with supports and leave them in place if you are feeling lazy. I wanted the open space so splitting it seemed the best way for me.
I recommend printing the spacer with fire resistant Prusament PETG V0 if you have it.
