Segments to be screwed to a darts backboard and underneath a dartboard protection ring. It provides a platform to mount a strip of WS2812 or similar LEDs so that through autodarts > darts-hub, one can see light effects based on what you have thrown in Autodarts games.

Ring has an outmost diameter of 615mm and you need 6 x segments printed and 12 small wood screws to attach to your dart backboard. 

You will need a printer capable of 307mm prints as that is the max distance of the model.

Print upside down with supports for the screw-tabs.
