Valve Index Trigger Reinforcements

The Valve Index “Knuckles” controllers have triggers that are prone to breaking along the internal hinge axle due to very thin plastic used in the hinge design. This is an insert you can add to the trigger that will add about 60% more plastic (0.6mm x2) to the main weak areas, plus spread out the upward hinge forces across more area using two tabs. This will theoretically increase your trigger's durability, but I have no way to actually test how much of a difference this makes in practice.
