Our Home Depot deck Umbrella got blown over in the wind and the mechanism that tilts and locks the umbrella broke. Printed using PLA tough, 90%infill, gyroid pattern. the pin on the button part is to hold the spring. Insert the rectangular part into the umbrella pole and then fit the round button part over the protruding end. Use glue to secure. Not as strong as the old metal piece so don't leave umbrella open in the wind.
