Patio Set Umbrella Holding Ring

I bought a patio dining set, which includes a table, some chairs, and an umbrella. The umbrella goes through the center of glass surface of dinning table. So there is a plastic ring to prevent direct contact to avoid shatter the glass and also fills the gap between the umbrella and the glass. Unfortunately I lost that plastic ring, so I printed one, at that time it was with my Wanhao i3. After 5 year, the PLA ring has been sitting outside under direct sunlight, rain, snow, hail, and extreme hot/cold weather. It's still holding. So I think it's a good reminder for me about the old days. As a result, I re-printed the same design with my X1C, and uploaded this model/profile here, hoping it can still benefit others. Dimension wise, the ring has a inner diameter of 41mm, and fit in the hole of diameter 51mm (or larger). This should be the pretty common size for the umbrella of patio dinning sets.
