Umbrella Holder for Balcony Railings

thingiverse

Mount two umbrella holders with cylindrical main shafts on your balcony railing, which should have at least two horizontal rectangular bars with vertically aligned inside edges. Rubber inserts prevent slipping sideways while ledges stop them from sliding downwards. To install an umbrella: First place one holder on the topmost rectangular bar as desired, then fasten it with two Velcro tapes. Next, mount the second holder directly below the first one onto the lowest rectangular bar. Finally, insert your umbrella and secure its height using hex bolts and wing nuts. A set of simple size adapters can expand compatibility for a wide range of diameters. Key features include stability, easy removal, adjustability, non-scratching design. First posted on Quirky.com. You'll need M6 (or preferred) screws with winged nuts, four Velcro strips matching railing circumference and 21mm wide, and 3mm or thicker rubber sheets. After customizing holders to your preferences, print them. Cut rubber sheets to fit indents, attach holders to railings using Velcro tapes, slide in the umbrella, and adjust height with screws.
