Garden Swing Part

This is a part that holds the canopy for a garden swing, purchased at Walmart. It is my first design project with Fusion 360 and also my first 3D print. I used Inland PLA plus filament. It's held up for a month through a couple storms and 90 degree heat, but I expect it will not be that durable, and I will replace it with a PETG part if it breaks. The Hirth joint (circular toothed section) is 49 mm in diameter, with 36 teeth. The two holes are for 6 mm screws and are 24 mm apart, center to center. The 6 mm screws may need to be replaced with slightly longer screws because I made the holes a little deeper (this is where the old part broke). The slot is for a rod around 18 mm in diameter.
