Geoffs Banana Plug Binding Post Replacement Cover

I required a Red housing for my Power Supply, but I only had 2 Black ones available, so I extracted the brass insert and inserted it into the nifty housing. You might need to drill or ream out the center to ensure a proper fit, and heating the ABS material is also highly recommended. If the housing becomes too loose, you can always use super glue for reinforcement.
