Parametric Patio Umbrella Base Adaptor for patio umbrellas to fit in larger bases.

My Patio umbrella has a smaller diameter hole than the weighted base I have. So I made this adapter to make umbrella sit tight and plumb.

The STL file here has umbrella diameter of 1.35 in and base diameter of 2.025 in

I used PETG for temperature resistance

Here is the onshape link to adjust parameters as needed. Just adjust the named variables for your umbrella pole diameter and base diameter
