Not sure how much this is common knowledge, but the stand that came with Kid Icarus Uprising for the 3DS can be used as a pretty good stand.
It even has a cut out at the bottom which means you can charge it at the same time and it's long enough that if any games support Tate mode in the future, it will support the Switch that way as well.
The only real drawbacks is that it only has one angle and as you can see it leans back a bit too far for my preference but it's still fine. Also it blocks portions of the back vents, but not completely. I'm sure you can modify the stand if it's something that worries you (drilling holes in the plastic seems like the easiest way, off the top of my head), or what I do is position the bottom of the Switch further out where it rests on the bottom to give some room for air to pass through.
Seems like a good additional solution if you already have one laying around, or can find one for cheap online.
