Wanhao i3 Plus - Heated Bed Bushing

Inline with the September 2016 Wanhao i3 Plus issue I have created a bushing to sit between the heated bed and the coiled spring, this will ensure the bed is insulated and cannot be scratched by the spring causing a short circuit and possible electric shock / fire risk.
