Drip watering tube stake

This was a request by my grandfather to make a stake to hold his drip watering tubes for his garden. They hold a 1/4 inch outer diameter tube on the top and are a little over six inches long. They should probably be made in abs or other high temperature plastic if you will be putting them outside in direct sunlight or high temperatures. I made my originals in PLA and they start to warp in 100*F days.
