The hole for my umbrella was too big so the umbrella was standing all crooked, this adapter solved it.

Ground hole diameter: 49,5mm
Umbrella pole diameter: 38.5mm

I put a rubberband between the umbrella and the adapter for now, so it will stay on the pole. I didn't want to glue it yet.

Printed in PLA for size check, final model in ASA for UV and water resistance.
