About this 3D model

When making pens, its necesary to glue a metal tube into a piece of material so that it can be turned on a lathe. Often this uses instant glue. Since instant glue will not stick to silicone rubbver, a silicone rubber plug can be used to prevent glue from getting into the center of the metal tube. This project design ifs for a simple mold for making silicone rubber plugs. The silicaone rubber is mixed in atwo parts and poured into the mold.
