I created an action figure stand which works with my 90's Reboot action figures as well as 90's star trek TNG and X-men figures.

There are plenty on here already but I prefer designs that are simple geometric because I think it prints cleaner and easier. This is simple two cylinders. I have made a 25mm version for a small foot print. But it doesn't provide a lot of support for flimsy figures so I made a 45mm one too.

I made the peg 3.1mm which I find fits snug but not too tight. By comparison my star trek TNG action figures come with official stands and I find they fit too tight.

Some models are ok with 1 25mm, some need two. Some are better with a 45mm. I picked these two diameters with very little thought put into it. I didn't really experiment with weight distribution or leverage.
