Patio table umbrella hole cover

thingiverse

This is a basic plastic solution for protecting the hole in a patio table where an umbrella would typically go. The .stl file accommodates a standard-sized 52-56mm umbrella hole which appears to be common here in the United States. The upper cover spans across a diameter of 60mm. For those seeking different measurements, the corresponding .scad file can be obtained and OpenSCAD used to alter the dimensions based on the guidance provided within the file. Adjustments made to parameters result in varied measurements that can then be exported as an STL for printing purposes. The code utilized here is brief, comprising merely 5 lines. To ensure success with this design, the recommended settings include a 0.3mm layer height, and the print should face downwards from the top-cover side when utilizing a Printrbot Simple Metal to produce results within approximately 22 minutes.
