You can chose your preferred sizes by changing it in fusion parameters eg. (diameter, height, width, thickness of the walls…)
It can be few rings in one installation
You can also pick which walls should light.
Tips and Instructions:
When you chose desire diameter and write it to parameters make sure that highest element is smaller than your print bed size. If not change number of parts to bigger number.
After printing all parts slide them together as in design.
Than rotate ad least two walls to connect all parts.
I used tied at ends insulated steel cable to hang it and solder it to provide 12V.
One line solder to + Second to - on opposite side. Works as charm.
It is better to use hot glue than relay on preinstalled led double side tape.
To Insert white wall just take ring apart where the led strip ends (make sure to start gluing it at the end of the part not in the middle) and gently separate it just enough to make room for sliding part.
