Plug for Running boards

This is a basic plug to fit Storyteller running boards.  These running boards are sold under many names such as Steelcraft and TAC.  I recommend to print with strength setting - multiple shells, low infill etc.  I usually do as a two color print and make 50 at a time.  Dog 1 is taller and more durable.  Dog 2 is better for bare (human) feet. 

These are designed for a tight fit and should not rattle.  Use a rubber hammer or similar to insert.  Your printer may have different calibrations and you might need to scale up or down a percent or two.
