This is my first printing project, a simple umbrella stand that can be installed from one side. It consists of two parts, where the lower part only has an additional edge to prevent the rod from going through. The model is designed for a 40x40 mm square railing and is suitable for rods with a diameter of 25 mm. You will need 3 M5 nuts and 3 M5 hexagonal screws with a length of 20-30 mm.
