Wooden Pepper Grinder Fix

For anyone with a wooden pepper grinder you may find that over time with heavy usage the internal metal rod wears a circle in the top wood piece where the wood used to be square shaped. Once this happens the grinder is essentially unusable unless you print and press fit this piece in place. Depending on how worn yours is you made need to drill the center out to allow this piece to press in. You want a tight fit for proper operation and so glue isn't necessary.
