Screw-on umbrella holder
thingiverse
I drew inspiration from oldcyclist's magnetic umbrella holder and transformed it into a screw-on version that demands a bit more effort to install. However, I didn't have any magnetic walls at my disposal, so that was out of the question. The holes are precisely 3.5mm in diameter, making them perfectly compatible with the counter-sunk screws I had on hand.
