What stands are suitable for NECA's TF2 action figures?

Posted in Action Figure Chatter

Hi guys, I was hoping you guys might know the answer to this!

I recently brought NECA's Team Fortress 2 action figures, but the damned things won't stand up! This is probably due to the top-heavy design of the characters and their thin ankles. I notice there's holes in their heels for some kind of stand. They didn't come with a stand, and there's no mention of a stand on NECA's website, so it looks like this is some kinda BYO stand situation. Any clues what stands would be suitable and where I would be able to buy them? As a side note, I notice the holes are actually hexagonal, not round. Is this unusual?

Thanks!
