Granboard 3S

Redesigned the LED Ring bracket to fit the 3S version of the Granboard, works with Lt_AldoRaine's Dartboard LED Ring: https://www.thingiverse.com/thing:4753272. Brackets are extremely tight snapping to ring and board and hold very well. Also look to use the ring connector from ketonk: https://www.thingiverse.com/thing:5254803. This makes it extremely simple to print and assemble without having to glue anything.
