This is my clip on umbrella light. There are 4 versions of this clamp inside. There is a tilted and straight version both with a solid or open bottom. They will light up your patio umbrella and look spectacular.
The "Open" version on the bottom use these special remote controlled LED tea lights. They simply press into the bottom but have the advantage of being remote controlled with various color options with a dedicated white LED.
You can point these up or down the umbrella pole depending on the light you need.
The other version has a closed bottom so you can place any sort of tealight in it. I have used these tea lights successfully on many projects and they are very inexpensive.

This is a flag clip that will keep your flag attached to the rod and keep it from moving. My wife had lost one of the flags she had and asked if I could create something to keep it in place. This works perfectly. I printed these in TPU however you could easily use PLA as well. The TPU has the added flexibility so they seemed to hold on quite well. The rod is a 5mm rod that they attach to. You can easily resize these large or smaller in the slicer to fit your flag rod.
