To construct an optical LED ring around a dartboard, controlled via WLED, I needed a closed ring to direct the light forward and prevent unwanted scattering to the rear.
For this, I framed the dartboard and developed and tested several versions of the ring. The version offered here has proven to be the best in practice.

Assembly instructions:
The ring is mounted directly onto a wooden board and can be easily screwed on.
Additionally, a separate spacer file is required, which I will also upload.
For assembly, two spacers without a hole and one spacer with a hole are required.

Printing notes:

• The ring is designed for stability and easy assembly.
• I recommend using matte, opaque filament to ensure the best possible light guidance.

Additional information:
Have fun printing and installing!
