I live next to the green of a wide-open par 5, and I seem to collect several buckets a year of the less than perfect shots. Looking around the garage, I remembered something similar I had seen posted elsewhere and thought I would give it a whirl. My wife says it is too heavy to write with, but oh well. Thinking of putting it in a cast-off / old persimmon club head as a pen holder.
Due to the shortness of the ball (upper part), I used an extra Euro tube for the "tee" to get some extra length. Tee is made of a scrap of maple and I had enough pen parts laying around to complete it.
Comments, etc. welcome!
