This is designed for use with Gene's recommended LED rings. The idea is to stand the ring off from the bottom of the effector so it doesn't touch the universal joints, thereby avoiding any "delta arm blues" type problems and generally providing a cleaner installation. It also secures the wires, so you don't have to worry about the solder joints failing after it's been in use for awhile. You need a few zip ties, but no other fasteners.
The LED mount also has recesses to accommodate my E3D mount, in case you have an E3D mounted under your effector. If it's mounted from the top, it won't matter.
