Many darts companies sell these LED rings for a lot of money. This one will cost you no more than 20€.
Things you need:
Print the following parts:
After printing remove all elephant foots from the segments and smooth the ends with sand paper. Connect the segments using the UHU plast or aceton. It will dissolve the ABS and weld the parts together (doesn't work with other materials). Use the connector pieces to reinforce the glue points as shown in the pictures. Attach the feet with Uhu plast and glue two magnets to each foot with super glue. Finally put your LED strip on the inside of the ring. If the adhesive strip of the LED's isn't strong enough like mine, fix it with some hotglue.
The assembly will take some time, but you will get a nice looking and very sturdy lighting ring which will easily survive incoming darts.
