Umbrella brackets

When we had some sun earlier this year I bought a sun shade umbrella for our patio.

The big concrete stand was getting in the way a bit so I've made some brackets attached to the very heavy table.

I managed to bend a spring clip nut back on itself to fit it tightly to the inside of the bracket.

I 3D printed the knob for the M5 bolt.

To protect the pole from the end of the bolt I heated up a strip of plastic and folded it over the bracket with the bolt passing through the outside flap.
